Question

Triangle PQR has vertices P(-2,6), Q(-8,4), and R(1-,2). It is translated according to the rule .

What is the y-value of ?
-18
-16
-12
-10

Answer 1

I can't solve it as written because the translation rule is missing and R's coordinate looks misprinted ("R(1-,2)"). Could you confirm:
- Is R = (1, −2) or R = (1, 2)?
- What is the translation rule (of the form (x,y) → (x + a, y + b))?

Method: if the rule is (x,y) → (x + a, y + b) and R = (1, −2), then the new y-value is −2 + b. Once you give a and b I’ll pick the correct choice.
