Graph the image of rectangle STUV after a reflection across the line x = -2 S(3,1), T(4, 1), U(4, 9), V(3, 9)

 see image

Step-by-step explanation:

Draw line x = -2. Count how many units away each point is from line x = -2 and  create the new points the same number of units away from line x = -2 but in the opposite direction.

S is 5 units to the right of x = -2. The new point S' is 5 units to the left of x = -2.

T is 6 units to the right of x = -2. The new point T' is 6 units to the left of x = -2.

U is 6 units to the right of x = -2. The new point U' is 6 units to the left of x = -2.

V is 5 units to the right of x = -2. The new point V' is 5 units to the left of x = -2.
