Question 923972
Hint:


Label the points


A(-4,-2)
B(2,-10)
C(8,-5)
D(2,3)



The quadrilateral has these sides: AB, BC, CD, AD


You need to show that AB is parallel to CD and BC is parallel to AD


Recall that two lines are parallel if their slopes are equal. So you need to show the two slopes are equal which means you need to use the slope formula to compute the slopes.
