Question

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

(–2, 0)
(0, –2)
(5, –7)
(5, –2)

Answer 1

`B(-5,0)\rightarrow B'(0,-2)`

Explanation:

From the diagram, B has coordinates
`(-5,0)`.

We want to find the coordinates of B' after a translation by the rule;

`(x,y)\rightarrow(x+5,y-2)`,

We apply the rule to obtain;

`B(-5,0)\rightarrow B'(-5+5,0-2)`,

This implies that;

`B(-5,0)\rightarrow B'(0,-2)`

Therefore the correct answer is B

Answer 2

we know that
the coordinates of point B ( -5,0)

the translation has the following rule
(x,y)--------> (x+5, y-2)
so
(-5,0)-----> (-5+5,0-2)-----> (0,-2)

the answer is
(0, –2)
