Question

a triangle is translated 4 units to the left and 3 units down. what is the new y - coordinate of a vertex originally at (10, 8)? the new y - coordinate is y = □. type your answer in the box.

Explanation:

Step1: Recall translation rule for y - coordinate

Translation down affects y - coordinate.

Step2: Subtract the number of units translated down

The original y - coordinate is 8 and it is translated 3 units down. So, the new y - coordinate is $y=8 - 3$.

Answer:
