2. What is the constant rate of change between the quantities in the table? Hours Total Worked Earnings (S) 15 138.75 20 185.00 203.50 222.00 A. . $6.74 per hour B.$9.25 per hour C. $23.13 per hour D. $0.11 per hour

y - 25 = 2 ( x - 10 ) should be the answer

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
