Which point lies on the equation y = x + 5?

Answer and explanation

Correct answer: (2, 7)

The governing concept is checking whether an ordered pair belongs to the graph of a linear equation. A point (x, y) lies on y = x + 5 only when its y-coordinate equals the value obtained from x + 5. For option B, x = 2, so x + 5 = 2 + 5 = 7, exactly the given y-coordinate. Therefore (2, 7) lies on the line and option B is correct. The distractors fail under direct substitution: for (5, 5), the equation requires y = 10; for (7, 2), it requires y = 12; and for (0, 4), it requires y = 5. None of those coordinate pairs satisfies the equation. This verification also means that the graph passes through B, making the answer unique.
