Exercise 26 Page 189

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

Slope: 0.5
y-intercept: 7

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+ bLet'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-7=0.5x
AddEqn

LHS+7=RHS+7

y-7+7=0.5x+7
AddTerms

Add terms

y=0.5x+7

Below we have highlighted the slope m and y-intercept b. y= 0.5x+ 7 We can see that the slope is 0.5 and the y-intercept is 7.
