Exercise 38 Page 320

What do m and b represent in y=mx+b?

Slope: 6
y - intercept: (0,0)

Practice makes perfect

Equations in slope-intercept form follow a specific format.

y= mx+ b In this format, m represents the slope of the line and b is the y-intercept. Let's rewrite our equation in this format. y= 6x ⇒ y= 6x+ 0 We can see that the slope is 6 and the y-intercept lies on the point (0, 0).
