When slope =0, the line is essentially horizontal.

That is, for every point on x, the value of y is the same.

So the formula you want to use is y = mx + b. b is the y intercept and m is the slope.

Since the slope is 0: y=0x + b

To find b substitute -4 for x and -2 for y: -2=0(-4) + b, b=-2(-4)=

Stacy,

b = -2 therefore since the lines has no slope (m=0) it is horizontal with all values of x where y=-2 including it's intercept and (-4,-2)

Stacy, since the slope is zero, y = b, which means that it's a constant. No matter what value of x you choose, y is the same, so its a horizontal line.

Since it's a horizontal line and you're given that (-4, -2), then at x = -4, y = -2 = b.

Hope that helps!
