Draw the image LKM under the transformation (x, y) → (x + 3, 2y). is the transformation a rigid motion? why?

Question

the Preimage is L(-3,2) K(-4,5) M(-1,1)

Answer 1

For this transformation 3 will be added to the x coordinate and the y coordinate will be multiplied by 2.

For example, for point L(-3,2), L' would be (-3+3,2*2) = (0,4).

K and M would be transformed in the same way.
