Question

A translation is applied to the triangle formed by the points A(−1, 4) , B(−1, 10) , and C(3, 6) . The image is the triangle that has vertices ​ A′(3, 4) ​, ​ B′(3, 10) ​​, and C′(7, 6) ​.

Answer 1

4 units to the right

Explanation:

I took the test, good luck you guys!

Answer 2

we have that

The coordinates of the pre-image and the image of the triangle are

`A(-1,4)----->A'(3,4)`

`B(-1,10)----->B'(3,10)`

`C(3,6)----->C'(7,6)`

so

The rule of the translation is

`(x,y)-------> (x+4,y)`

That means

The translation is
`4` units to the right

therefore

the answer is

The translation is
`4` units to the right
