Exercise 86 Page 423

Substitute the slope and y-intercept into the slope-intercept form.

y=1.25x-3.79

Practice makes perfect

Lines written in slope-intercept form follow a certain format.

y= mx+ b In this form, m is the slope and b is the y-intercept. By substituting m= 1.25 and b= -3.79 into this equation, we can write the line's slope-intercept form equation. y= 1.25x+( - 3.79) ⇔ y= 1.25x- 3.79
