Exercise 39 Page 313

What do m and b represent in the slope-intercept form?

Slope: 9
y-intercept: 1/2

Practice makes perfect

Equations in slope-intercept form follow a specific format, where m represents the slope of the line and b is the y-intercept.

y= mx+ b Let's rewrite our equation a little bit so that it more closely resembles this format. This will make it easier to identify the features of the equation. y-9x=1/2 ⇔ y= 9x+ 1/2 We can see that the slope is 9 and the y-intercept is 12.
