Find the slope of the line that passes through the given points.<br> (-5,6) and (2,6)
CaHeK987 [17]

Answer:

0

Step-by-step explanation:

Your slope would be 0. To find the slope of a line given two points, you find the change in y over the change in x.

In this case, the change in y was 6 - 6 which equals 0.

The change in x was -5 - 2 which was -7.

Since your numerator is 0, 0 divided by anything is automatically equal to 0 no matter what the denominator is.

Therefore, your answer would be 0.

I hope this helped :)
