In the second one I'm pretty sure you just measure the length of the points.
I hope this helps for question a=16
I hope this helps for question b=12
The answer is yes she incorrectly graphed using the points (-2,4) instead of the point (4,-2). This is the answer because if you solve the equation given you should get y=-3/5x+2/5 so a and e will be wrong and if you plug one of the points in you will give a untrue statement so its not d so you are left with b and c so you plug in the end request and you get a true statement with b equaling -2 if you plug in 4 in for x
The answer is A. (2,2)....
