The line is horizontal, passing through the yy-axis at (0,-8)(0,8)

m =0m=0

Explanation:

y = -8" "y=8 is the equation of a straight line and can therefore still
color(white)(...................) be written in the form y= mx+c

Notice that there is no x- term... This means that it is 0 and the equation is actually:

y = 0x -8
m =0

No matter what value of x is used, the value for y will still be -8

The line is horizontal and therefore has a slope of 0
