Exercise 7 Page 543

What information does a slope-intercept form equation give you?

Practice makes perfect

Equations written in slope-intercept form follow a specific format. y=mx+ b In this form, m represents the slope of the line and b represents the y-intercept. Below we highlight the slope m and y-intercept b. y=x ⇕ y=1x+ 0 The slope is 1. The y-intercept is 0, so the graph crosses the y-axis at the point (0, 0).

Graphing the Equation

A slope of 1 means that for every 1 unit we move in the positive horizontal direction, we move 1 unit in the vertical direction. m=1/1 ⇔ rise/run=1/1 To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
