Exercise 9 Page 123

Substitute the given point and slope into the slope-intercept form equation.

y=2/3x+9

Practice makes perfect
Equations in slope-intercept form follow a certain format. y=mx+ b

In this format m is the slope and b is the y-intercept. The line has a slope of 23 which means that we can substitute m=23. y=2/3x+ b Since the x-coordinate of the given point equals 0, its y-coordinate 9 is the y-intercept b of the equation. y=2/3x+ 9
