Question

If the triangle on the grid below is translated by using the rule (x, y) right-arrow (x + 5, y minus 2), what will be the coordinates of B prime?

Answer 1

`B'(x,y) = (0,-2)`

Explanation:

Given

The attached grid

Translation rule:
`(x,y) = (x + 5, y - 2)`

Required

Determine the coordinates of B'

First, we have to write out the coordinates of B

`B(x,y) = (-5,0)`

Next is to apply the translation rule
`(x,y) = (x + 5, y - 2)`

`B(x,y) = (-5,0)` becomes

`B'(x,y) = B(x+5,y-2)`

Substitute -5 for x and 0 for y

`B'(x,y) = (-5+5,0-2)`

`B'(x,y) = (0,-2)`
