Exercise 50 Page 79

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

Slope: -0.8
y' -intercept:' (0,0.4)

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=0.4-0.8x
y=-0.8x+0.4
The given equation is already in this form. Below we have highlighted the slope m and y-intercept b. y= -0.8x+ 0.4 We can see that the slope is -0.8 and the y-intercept is (0, 0.4).
