Question

what is the image of (x,y) after a translation of 3 units to the right and 7 units down? A.) (x-3,y-7) B.) (x+3,y-7) C.) (x+3,y+7) D.) (x-3,y+7)​

Answer 1

B.) (x+3, y-7)

Explanation:

x-coordinates increase farther to the right of the y-axis. Increasing the x-coordinate of a point by 3 will move the point 3 units to the right.

y-coordinates increase farther above the x-axis. Decreasing the y-coordinate of a point by 7 will move the point 7 units down.

To translate a point (x, y) 3 units right and 7 units down, the new coordinates need to be ....

(x +3, y-7) . . . . . . . . matches selection B
