Every point on this line has the same y coordinate, which is -2. There is no "rise" at all so rise = 0 while the "run" is any nonzero value you want. If you made the run be say 2, then
slope = rise/run = 0/2 = 0
The slope is 0
Answer: D) 0
note: all horizontal lines like this have a slope of 0. It doesn't matter what the y intercept is
Slope addresses how steep the line is. Since the line is flat, it neither slants up or down. Therefore, there is not slope or slant, thus the slope is 0. There is a nonexistent change in the y-axis, but a change in the x-axis.
