The measure of the fourth interior angle in the quadrilateral is 145
Slope is the change in y over the change of x. So for the first two points are 4-4 over 6 +2, that turns into 0 over 8 and that's just 0=slope
The second one you just do that same thing and then the answer is -7 over 0 which is an undefined slope
