The graphs of two linear equations intersect at \\(15,2\\). What is the value of \\(x\\) at this point?
Answer and explanation
Correct answer: 15
In an ordered pair \\( (x,y) \\), the first coordinate represents \\(x\\) and the second represents \\(y\\). Therefore, for the intersection point \\( (15,2) \\), \\(x=15\\). The value 2 in option A is the value of \\(y\\), not \\(x\\). Exam tip: Always read the coordinates in the order \\(x,y\\).
