Which ordered pair would form a proportional relationship with the point graphed below (60,-20) a: (-10,30) b: (30,-15) c: (-30,10) d: (80,-30)

The point (-30, 10) will from a proportional relationship with the point (60, -20).

A proportional relationship takes the form of y = kx. In other words, we are just multiplying x by a number to change it into y. 

In this case, if we multiply x by -1/3 in both situations, we will get the correct y value.

Iwould think that the correct answer is 8.1
