ANSWER

R'(-3,6)

T'(-3, 3)

D' (-5, 3)

C' (-5, 7)

Explanation:

Given information

In the figure given, the image in the graph consists of 4 vertices which are listed below as;

R(1,1)

T(1, -2)

D(-1, -2)

C(-1, 2)

According to the question, we were told that the image is translated into 4 units to the left and 5 units to the up to create another quadrilateral R' T' D' C'

To translate a function to the left, means a negative value will translate it to the left

Hence, 4 units to the left will be (x - 4)

To translate a function to the up means a positive value to the y-axis

Hence, 5 units to the up will be (y + 5)

Therefore, the general rule for the translation is

(x, y) -----------------------> (x - 4, y + 5)

Since the original coordinates are;

R(1,1)

T(1, -2)

D(-1, -2)

C(-1, 2)

Using the general rule above

R(1,1) ----------------> R'(1 - 4, 1 + 5)

-----------------> R'(-3, 6)

Therefore, R(1,1) is translated to R'(-3, 6)

T(1, -2) ---------------> T'(1- 4, -2 + 5)

----------------> T'(-3, 3)

Therefore, T(1, -2) is translated to T'(-3, 3)

D(-1, -2) ----------------> D'(-1 - 4, -2 + 5)

----------------> D' (-5, 3)

Therefore, D(-1, -2) is translated to (-5, 3)

C(-1,2) ----------------> C'(-1 - 4, 2 + 5)

C(-1, 2) ---------------> C'(-5, 7)

Therefore, C(-1, 2) is translated to C'(-5, 7)

R'(-3,6)

T'(-3, 3)

D' (-5, 3)

C' (-5, 7)
