If the intersection point of two linear equations on the graph is (7, 13), what is the value of y?
Answer and explanation
Correct answer: 13
In an ordered pair (x, y), the first coordinate is the x-coordinate and the second coordinate is the y-coordinate. Therefore, in (7, 13), y = 13. The value 7 is the x-coordinate, not the y-coordinate. Exam tip: the second coordinate of (x, y) always gives the value of y.
