What is the (y)-intercept of the line (y=7x+0)?
Answer and explanation
Correct answer: \(0\)
In the form \(y=mx+c\), \(c\) is the \(y\)-intercept. Here, in \(y=7x+0\), the constant term is \(0\), so the \(y\)-intercept is \(0\) and the line passes through the origin \((0,0)\). The number \(7\) is the slope, not the \(y\)-intercept. Exam tip: put \(x=0\) to find the \(y\)-intercept.
