Section 5.1: Writing Linear Equations in Slope-Intercept Form
In this lesson we will learn how to write an equation of a linear equation in slope-intercept
form.
To write an equation using slope-intercept form you must know two things about your line:
slope of the line.
1. The _________
y-intercept of the line.
2. The __________________
Example 1:
(b) is –4.
Write an equation of the line whose slope (m) is
y= mx + b
