Question

If the triangle on the grid below is translated by using the rule (x, y) right-arrow (x minus 2, y + 2), what will be the coordinates of A prime? On a coordinate plane, triangle A B C has points (negative 2, negative 2), (negative 2, negative 4), (2, negative 4). (–4, 0) (0, 4) (0, 0) (–2, 2)

Answer 1

A, (–4, 0)

Explanation:

Answer 2

Coordinates of A prime will be (-4,0).

Explanation:

Given:

ABC is a triangle on a grid with its coordinates in (x,y).

The coordinates are as follows:

`A = (-2,-2)`

`B = (-2,-4)`

`C = (2,-4)`

According to the question.

The points are translated by (x-2,y+2) rule.

We have to find A prime i.e A' the coordinate of A after it is translated.

In translation we move the coordinates without rotating and resizing.

So

Point A after translation will be called A'.

⇒ A =
`(-2,-2)`

Subtracting 2 with the 'x' value and adding 2 with the 'y' value coordinate.

⇒ A' =
`(-2-2,-2+2)`

⇒ A '=
`(-4,0)`

So the value of A prime after translating it by (x-2,y+2) is (-4,0).
