Exercise 81 Page 423

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

y=- x+4

Practice makes perfect

Lines written in slope-intercept form follow a certain format. y= mx+ bIn this form, m is the slope and b is the y-intercept. Let's substitute m= -1 and b= 4 into this equation.

y = mx+b

m= -1, b= 4

y = -1x+ 4

Multiplication Property of -1

y = - x+4

Now we have the line's slope-intercept form equation. y= -x+ 4
