Question

Triangle PQR is drawn with coordinates P(0, 2), Q(0, 5), R(1, 4). Determine the translation direction and number of units if Q′(9, 5).

9 units down

9 units up

9 units to the right

9 units to the left

Answer 1

Answer: 9 units to the right (choice C)

Reason:

Focus on Q(0, 5) and Q′(9, 5)

More specifically, focus on the x coordinates. We go from x = 0 to x = 9, which means "shift 9 units to the right" since we added 9 to the old x coordinate to get the new x coordinate. The y coordinates stay the same.

The translation rule is
`(\text{x},\text{y}) \to (\text{x}+9, \text{y})`
