Question

Which of the following ordered pairs is part of the solution set for the equation y = 3x? - 4?
Option #1: (-2, - 8)
Option #2: (2,8)
Option #3: (-4, 0)
(1 point)
Option #
is part of the solution set for the equation.

Answer 1

I need to check the exact equation — is it y = 3x − 4 or y = 3x^2 − 4?

- If y = 3x − 4:
(-2, −8): 3(−2) − 4 = −10 ≠ −8
(2, 8): 3(2) − 4 = 2 ≠ 8
(−4, 0): 3(−4) − 4 = −16 ≠ 0
→ None of the options fit.

- If y = 3x^2 − 4:
(-2, −8): 3(4) − 4 = 8 ≠ −8
(2, 8): 3(4) − 4 = 8 = 8 ✔
(−4, 0): 3(16) − 4 = 44 ≠ 0
→ Option #2 (2, 8) is a solution.
