Question

What is the slope of (-4,-9) and (4,-9)

Answer 1

Answer: slope=0

Step-by-step explanation:

usually slopes are found by taking

change in y

-----------------

change in x

but in all horizontal lines (matching y values, -9 in this case) the line has no slope as it doesn't go up or down.

Answer 2

Answer: m (slope) = 0

Explanation:

The slope can be found through the equation (y2-y1)/(x2-x1)

(-4, -9) and (4, -9) can be: (x1, y1) and (x2, y2)

We can plug the variables into the formula above:

(-9-(-9))/(4-(-4) = 0/8

The slope is 0.
