Question

Which of the following is a result of shifting a circle with equation

(x - 1)2 + (y - 4)2 = 16

to the right 4 units?

A. The x-coordinate of the center of the circle increases by 4.
B. Both the x- and y-coordinates of the center of the circle decrease by 4.
C. The y-coordinate of the center of the circle increases by 4.
D. Both the x- and y-coordinates of the center of the circle increase by 4.

Answer 1

Answer: A

Explanation:

Since it’s a horizontal shift and not vertical only the x coordinate changes. That then means that since it’s shifting to the right that value would then increase. Giving you the answer of A.

Answer 2

C. The y-coordinate of the center of the circle increases by 4.
