Answer:
or zero.
Step-by-step 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 <em>undefined. </em>
In short the formula to find slope is:
-
