What is the \(x\)-intercept of the line \(4x+y=20\)?
Answer and explanation
Correct answer: (5,0)
The \(x\)-intercept is the point where the line crosses the \(x\)-axis, so \(y=0\). Substituting this into the equation gives \(4x=20\), hence \(x=5\). Therefore, the \(x\)-intercept is \((5,0)\). Remember that \((0,20)\) is the \(y\)-intercept because \(x=0\) there.
