(-5, -4) and (3, -4)
This is a multiple choice question but I don't see the answer that im coming up with. I think it's -4 but want another set of eyes.
A. 0
B. -1
C. Undefined
D. 4

Slope is delta y / delta x or more commonly called "Rise over Run".
In this case
The rise is -4 - (-4) = -4 + 4 = 0
The run is 3 - (-5) = 3 + 5 = 8
So 0/8 = 0
A is your answer

since both y coordinates are -4, the change in y is 0. that makes the slope 0 as long as the change in x is not 0 (if it were, we'd only have 1 point).

slope = y1-y2 / x1-x2
-4 - -4 / -5 - 3
= 0/-8
= 0

if the points are (x1,y1) and (x2, y2) the slope is (y2-y1)/(x2-x1)
in our case slope = (-4 +4)/ (-5-3)=0/-8=0
ie. A is the answer

A
if you graph the points they are a straight line
change in Y over the change in X
change in Y = 0

the slope is 0 hence the line is horizontal

slope = (y2-y1)/(x2-x1) = [4-(-4)]/[3-(-5)] = 0/8 so it's 0

You can the formula:
(y1-y2)
----------
(x1-x2)
(-4 - (-4) ----Changes to + 4
-----------
(3-(-8)----Changes to + 8
So, 0/8 slope = 0
A
