Consider the point B located at the coordinates (2,-1). First, dilate the point by a scale factor of 3 from the origin. Then, reflect that dilated point over the y-axis and label this point B.” What are the coordinates of B”?

Answer 1

(-6, -3)

Explanation:

The coordinate is at (2, -1), when using a dilation with a scale factor of 3, multiply the coordinates by 3.

(2, -1) ------> (2 x 3, -1 x 3) ----------> (6, -3)

When reflecting the point over the y-axis, take the opposite of the x coordinate.

(6, -3) ------> (-6, -3)
