Describe the effect of the transformation. (x,y)--->(x,-7y) A. Vertical translation of -7 units. B. Vertical stretch without reflection C. Horizontal translation of -7 units D. Vertical stretch without reflection Is the answer A

D.Vertical stretch with reflection It was supposed to say this

y---->7y would "stretch" it by a factor of 7 y ---- -7y would not only stretch it but also reflect it in the x-axis. so it looks like D after your correction of the wording
