Question

Point (21,28) is dilated by a scale factor of (-1/7) with a center of dilation on the origin. What are the new coordinates

Answer 1

Original value of x-axis =21

New value of x-axis = 21×(-1/7) = -3

Original value of y-axis =28

New value of y-axis = 28×(-1/7) = -4

Hence, the new coordinate is (-3,-4).

Answer 2

Explanation:

Original x-value = 21

New x-value = 21 * (-1/7) = -3.

Original y-value = 28

New y-value = 28 * (-1/7) = -4.

Hence the coordinates of the new point is (-3,-4).
