Answer:

  • B. (-1, 13) and (3, 5)

Step-by-step explanation:

Solve by elimination:

  • x² - 4x + 8 = -2x + 11
  • x² - 2x = 3
  • x² - 2x + 1 = 4
  • (x - 1)² = 2²
  • x - 1 = 2 ⇒ x = 3
  • x - 1 = -2 ⇒ x = -1

Find values of y:

  • y = -2(3) + 11 = 5
  • y = -2(-1) + 11 = 13

The pairs are:

  • (3, 5) and (-1, 13)

Correct choice is B
