24 I think is the answer but I'm not sure. Hope I helped:)
Answer: undefined
Step-by-step explanation:
The answer is undefined because when you plug in the points in the formula
y2-y1/ x2-x1 the denominator is 0 which makes it undefined. Also when you put it into a graphing calculator it will say that its undefined.
This is false, because the equation is then 12=2, which is incorrect.
Hope this helps!
