Answer 1

Answer:

The new points to the triangle will be:
$A(1,4)\\ B(1,1)\\ C(-1,1)$

Step-by-step 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 $C(-1,1)$.
