ANSWER
The slope between the two points is 0
EXPLANATION
Given that;
<em>(3, 8) and (-4, 8)</em>
Slope is defined as the gradient of a line
The formula for determining slope is given below as

Where
rise = y2 - y1
run = x2 - x1
So, we have

In the given point, let x1 = 3, y1 = 8, x2 = -4 and y2 = 8

Therefore, the slope between the two points is 0
