Which point lies on \(y = -3x + 7\)?
(0, 7), (2, 1) and (3, −2) all
Substitute each point's \(x\)-coordinate into \(y = -3x+7\) and check whether you get the given \(y\).
(0, 7): \(-3(0)+7 = 7\) ✓
(2, 1): \(-3(2)+7 = -6+7 = 1\) ✓
(3, −2): \(-3(3)+7 = -9+7 = -2\) ✓
All three points satisfy the equation. Hence the correct choice is all of them — option (4).
