Question

Which are the coordinates of the transformed point (3,-2) vertical stretch of 4 a. (3,2) b.(12,-2) c.(7,-6) d. (3,-8)

Answer 1

The given point is (3,-2).

The transformation is a vertical stretch of 4.

Vertical stretch can be obtained when we multiply the vertical coordinate by a factor, in this case, 4.

$(3,-2\cdot4)=(3,-8)$

Therefore, the right answer is D.
