Slope Intercept Form Worksheet With Answers

Quick Links :

Slope-intercept form is one of the most common forms of a linear equation, which is used to describe a straight line. It is written in the form y = mx + b, where m is the slope and b is the y-intercept. Understanding and working with slope-intercept form is essential for anyone studying algebra or other areas of mathematics.

In this article, we will explore the concept of slope-intercept form, how to convert equations to slope-intercept form, and provide a comprehensive worksheet with answers to help you practice and reinforce your understanding.

What is Slope-Intercept Form?

Slope-intercept form is a way of expressing a linear equation in the form y = mx + b, where:

• m is the slope of the line, which represents the rate of change of the line. A positive slope indicates a line that slopes upward from left to right, while a negative slope indicates a line that slopes downward from left to right.
• b is the y-intercept, which is the point where the line intersects the y-axis.

For example, the equation y = 2x + 3 is in slope-intercept form, where the slope (m) is 2 and the y-intercept (b) is 3.

Converting Equations to Slope-Intercept Form

Converting an equation to slope-intercept form can be done by rearranging the terms and isolating y. Here are the steps:

1. Write the equation in standard form (ax + by = c).
2. Add or subtract the same value to both sides of the equation to isolate the term with y.
3. Divide both sides of the equation by the coefficient of y to solve for y.

For example, consider the equation 2x + 5y = 7. To convert it to slope-intercept form, we can follow these steps:

1. Write the equation in standard form: 2x + 5y = 7
2. Subtract 2x from both sides of the equation: 5y = -2x + 7
3. Divide both sides of the equation by 5: y = (-2/5)x + 7/5

The resulting equation is in slope-intercept form, where the slope (m) is -2/5 and the y-intercept (b) is 7/5.
