Which point lies on the graph of the linear equation \(y=4x-2\) when \(x=3\)?

Answer and explanation

Correct answer: (3, 10)

Substituting \(x=3\) into the equation gives \(y=4(3)-2=12-2=10\). Therefore, the corresponding ordered pair is \((x,y)=(3,10)\). Options B and D interchange the \(x\)- and \(y\)-coordinates, while option A results from an arithmetic error. Exam tip: in an ordered pair, the first coordinate is \(x\) and the second is \(y\).
