Which point lies on the graph of \(y=3x-1\) when \(x=2\)?
Advertisement
Answer and explanation
Correct answer: \((2,5)\)
Substituting \(x=2\) gives \(y=3(2)-1=6-1=5\). Therefore, the point is \((x,y)=(2,5)\). In option A, the value of \(y\) is incorrectly taken as 3. In the exam, remember to write coordinates in the order \((x,y)\).
