Question

Which pair is a solution of y=5x-2

Answer 1

Given the values 1,2 and 3 for x, we have the following:

`\begin{gathered} x=1 \\ \Rightarrow y=5\cdot(1)-2=5-2=3 \\ y=3 \\ x=2 \\ \Rightarrow y=5(2)-2=10-2=8 \\ y=8 \\ x=3 \\ \Rightarrow y=5(3)-2=15-2=13 \\ y=13 \end{gathered}`

therefore, the pair that is a solution of y=5x-2 is (3,13)
