Question

Which ordered pair would form a proportional relationship with the point graphed below? 40 (-20,40) 30 20 10 -40-30-20-190 10 20 30 40 x -20 -30 -40 0 (-40, 20) 0 (-10.-20) O (15, -30) O (5, -15)​

Answer 1

(15,-30)

Explanation:

By forming a proportional relationship with the marked point, what we are saying is that the same dilation if applied to each coordinates of the marked point will form the new point

The marked point is given as (-20,40)

If we dilate this by -0.75 units

That will give (15, -30)

So this forms a proportional relationship with the marked point
