Question

Triangle ABC is translated according to the rule (x,y) - (x + 2, y-8). If the coordinates of the pre-image of point B are

(4,-5), what are the coordinates of B'?
(2,3)
(1,-9)
(-3, 4)
(6-13)​

Answer 1

6, -13

Explanation:

Answer 2

(6,-13)​

Explanation:

We just have to substitute the given point into the transformation rule and simplify.

The rule is
`(x,y)\to (x+2,y-8)`.

We want to find the coordinates of B' if B has coordinates (4,-5).

We substitute x=4 and y=-5.

`B(4,-5)\to B'(4+2,-5-8)`.

Simplify to get:

`B(4,-5)\to B'(6,-13)`.

The last option is correct.
