Find the coordinates of the intersection of the diagonals of parallelogram wxyz with the following vertices: w (-1, 7), x (8, 7), y (6, -2) and z (-3, -2)

Check the picture below

in a parallelogra, the diagonals "bisect" each other, thus each one cuts the other in 2 equal halves.

that simply means in this case, where they intersect, is the midpoint of either diagonal... so let's use the midpoint of XZ then
