Question

which of these ordered pairs is a solution to this equation? y = 5x - 7 (3, 8) (1, 3)

Explanation:

Step1: Test \((3, 8)\)

Substitute \(x = 3\) and \(y = 8\) into \(y = 5x - 7\).
Right - hand side: \(5\times3-7=15 - 7=8\), which is equal to the left - hand side \(y = 8\).

Step2: Test \((1, 3)\)

Substitute \(x = 1\) and \(y = 3\) into \(y = 5x - 7\).
Right - hand side: \(5\times1-7=5 - 7=- 2
eq3\).

Answer:

\((3, 8)\)
