Question

1. a point a (x, y) is translated 7 units to the left and 2 units up. what is the mapping to the new point a?

$(x-7,y+2)$
$(x+2,y-7)$
$(x+2,y+7)$
$(x+7,y+2)$

Explanation:

Step1: Adjust x-coordinate (left shift)

Subtract 7 from $x$: $x-7$

Step2: Adjust y-coordinate (up shift)

Add 2 to $y$: $y+2$

Answer:

A. $(x-7, y+2)$
