**Algebra 1 – How to Graph a Linear Equation Using Slope and y**

- Step 1: Put the equation in Slope Intercept Form.
- Step 2: Graph the y-intercept point (the number in the b position) on the y-axis.
- Step 3: From the point plotted on the y-axis, use the slope to find your second point.
- Step 4: Draw your line using the two points you plotted (y-intercept (b) first, slope (m) second.

What is a linear line on a graph?

**Linear graphs**are one way of expressing these relationships, when graphed they give a straight line.

**Linear graphs**can be sketched or plotted. Plotting a Straight Line

## How do you graph a function?

Consider the

**function**f(x) = 2 x + 1. We recognize the equation y = 2 x + 1 as the Slope-Intercept form of the equation of a line with slope 2 and y-intercept (0,1). Think of a point moving on the**graph**of f. As the point moves toward the right it rises.2

## What is the graph of a linear equation in two variables?

Use slope and

**linear**equations in two variables to model and solve real-life problems. The simplest mathematical model for relating two variables is the**linear**equation in two variables y = mx + b. The equation is called**linear**because its graph is a line. (In mathematics, the term line means straight line.)3

## How do you draw a graph?

**How to Draw a Graph**

- Draw the x axis. Make a horizontal line on the paper.
- Draw the y axis. Make a vertical line that passes through the origin of the x axis.
- Calculate the values of y for several values of x.
- Mark the ordered pairs on the graph.
- You have created a graph of the function f(x) = 2x.

## How do you graph a point?

The center

**point**of the**graph**is called the origin and is written as the**point**(0, 0) because it's located at the zero**point**on the x-axis and the zero**point**on the y-axis. For example, to plot the**point**(3, -6), find the positive 3 on the x-axis and the negative 6 on the y-axis.5

## How do you make a graph?

- Get your data into Excel. First, you need to input your data into Excel.
- Choose a type of chart/graph to create.
- Switch axes, if necessary.
- Adjust your labels and legends, if desired.
- Change the Y axis measurement options, if desired.
- Reorder data, if desired.

## How do you graph an equation in standard form?

Graphing a Line in

**Standard Form**. When a line is in**standard form**, there are two different ways to**graph**it. The first approach is to change the**equation**to slope-intercept**form**and then**graph**it. The second approach is to use**standard form**to find the and intercepts of the line and connect the two.7

## What is the formula of a line graph?

The

**equation**of a straight**line**on a**graph**is made up of a y term, an x term, and a number and are written in the form of y = mx + c. The slope of the**line**is known as the gradient and is represented by m in the**equation**. The point at which the**line**crosses the y-axis is the c in the**equation**.8

## How do you graph a linear inequality?

**There are three steps:**

- Rearrange the equation so "y" is on the left and everything else on the right.
- Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
- Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

## How do you graph in science?

Calculate an average for the different trials of your experiment, if appropriate.

**Make**sure to clearly label all tables and**graphs**. And, include the units of measurement (volts, inches, grams, etc.). Place your independent variable on the x-axis of your**graph**and the dependent variable on the y-axis.11

## What is a solution in graphs?

The

**solution**of such a system is the ordered pair that is a**solution**to both equations. To solve a system of linear equations graphically we**graph**both equations in the same coordinate system. The**solution**to the system will be in the point where the two lines intersect.12

## How do you do linear graphs?

To

**graph**a**linear**equation, we can use the slope and y-intercept. Locate the y-intercept on the**graph**and plot the point. From this point, use the slope to find a second point and plot it. Draw the line that connects the two points.13

## How do you find y MX B from a graph?

To

**graph**the**equation**of a line written in slope-intercept (**y**=**mx**+**b**) form, start by**plotting**the**y**-intercept, which is the**b**value. The**y**-intercept is where the line will cross the**y**-axis, so count up or down on the**y**-axis the number of units indicated by the**b**value.14

## What is a good line graph?

**Line graphs**are used to track changes over short and long periods of time. When smaller changes exist,

**line graphs**are better to use than bar

**graphs**.

**Line graphs**can also be used to compare changes over the same period of time for more than one group.

## How do you write the slope intercept form of an equation?

- Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
- Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

## What is the slope intercept form of the equation?

The first of the

**forms**for a linear equation is**slope**-**intercept form**. Equations in**slope**-**intercept form**look like this: y = mx + b. where m is the**slope**of the line and b is the y-**intercept**of the line, or the y-coordinate of the point at which the line crosses the y-axis.17
