Can someone please help I pay £100

Answer 1

The new points to the triangle will be:

`A(1,4)\\ B(1,1)\\ C(-1,1)`

Explanation:

Because the reflection point is at
`x=2`, all x values will subtract their distances from
`x=2` to get their new values. The y values remain the same.

The starting values are:

`A(3,4)\\ B(3,1)\\ C(5 ,1)`

Point
`A` is 1 unit away from
`x=2`, so we'll subtract 1 from 2 to get the new x value:
`2 - 1 = 1`, so
`A(1,4)`.



Point
`B` is also 1 unit away from
`x=2`, so we'll subtract 1 from 2 to get the new x value:
`2 - 1 = 1`, so
`B(1,1)`.

Point
`C` is 3 units away from
`x=2`, so we'll subtract 3 from 2 to get the new x value:
`2 - 3 = -1`, so
`C(-1,1)`.
