Answer:
or zero.
Explanation:
The pair on the left is (-4, -5). The pair on the right is (1, -5).
In order to find the slope, you must first subtract the y in the first pair by the y in the second pair. Then what ever answer you get will be your numerator. Then, subtract the x in the second pair by the x in the first pair and that will be your denominator. So, in this case, it would be
which equals
. If a zero is the numerator, that means that the fraction is zero. If the zero had been on the bottom, then the answer would have been undefined.
In short the formula to find slope is:
-
