Question

Find the slope of the following graph.

Answer 1

Slope is defined as \[m = {\Delta y \over \Delta x} = {rise \over run}\]

In this case rise = 0, therefore slope is 0.

Answer 2

a horizontal line has a slope of 0, because there is no change in Y, no matter how much you change X

correspondingly, a vertical line has a slope that is undefined, because you cannot have a zero in the denominator.

Answer 3

The x-intercept of the line whose equation is 2x - 3y = 6 is

3
6
-2
