Thread: i have a paper past due and i am horrible at math please help me!

find the coordinates of the intersection of the diagonals of parallelogram PRYZ P(2,3) R(1,-2) Y(-5,-7) Z(-4,-2)

$\displaystyle X_C=\frac{X_P+X_Y}{2}=\frac{X_R+X_Z}{2}$

$\displaystyle Y_C=\frac{Y_P+Y_Y}{2}=\frac{Y_R+Y_Z}{2}$
