Answer and explanation
Correct answer: (4, 3)
A point lies on a line when its coordinates satisfy the equation. Testing option B gives 3(4) - 4(3) = 12 - 12 = 0, so (4, 3) is on the line. The other choices give 9 - 16 = -7, 3 - 8 = -5, and 6 - 4 = 2 respectively, so they do not satisfy the equation. Therefore B is unambiguous.
