Answer:
m=undefined
Step-by-step explanation:
the formula for slope (m) is (y2-y1)/(x2-x1)
here are the given points: (-5,0) and (-5,5)
we can label the points:
x1=-5
y1=0
x2=-5
y2=5
now substitute into the equation
m=(5-0)/(-5--5)
m=(5-0)/(-5+5)
m=5/0
m=undefined
the slope is undefined, because you cannot divide by 0
Let's start with what we know:

And we are trying to put it into this form:

Here is what it would look like:
