A triangle on a coordinate plane is translated according to the rule T–8, 4(x, y)?

Answer : (x, y) → (x - 8, y + 4)

Reason :

We have to see the way we can rewrite the rule T (x, y), which is the way that the triangle is writen on the coordinate plane and is going to be translated.

T : means that we are going to move - 8 units on the xaxis (8 units to the left), and that we are going to move + 4 units on the y axis (4 units up).

So another way to describe this is : (x - 8, y + 4).
