Because the reflection point is at $x = -1$ , all x values will subtract their distances from $x = -1$ to get their new values. The y values remain the same.

The starting values are:

$A(4,6)\\B(4,3)\\C(6,3)$

Point $A$ is 5 units away from $x = -1$ , so we'll subtract 5 from -1 to get the new x value: $-1 - 5 = -6$ , so $A(-6, 6)$ .

Point $B$ is also 5 unit away from $x = -1$ , so we'll subtract 5 from -1 to get the new x value: $-1 - 5 = -6$ , so $B(-6, 3)$ .

Point $C$ is 7 units away from $x = -1$ , so we'll subtract 7 from -1 to get the new x value: $-1 - 7 = -8$ , so $C(-8, 3)$ .

Step-by-step explanation:

x+y=21

2x+3y=51

x=-y+21

2(-y+21)+3y=51

-2y+42+3y=51

y+42=51
