For the line \(x+2y=8\), what is the value of \(x\) when \(y=0\)?
Advertisement
Answer and explanation
Correct answer: 8
Substituting \(y=0\) in the equation gives \(x+2(0)=8\), so \(x=8\). Therefore, the x-intercept of the line is the point \((8,0)\). The value 4 may result from confusing the coefficient 2 with the required calculation. Exam tip: To find the x-intercept, always put \(y=0\).
