In the form (y=mx+c), how is the (y)-intercept identified?
Answer and explanation
Correct answer: Constant term (c)
In the linear form \(y=mx+c\), \(c\) is the constant term and represents the y-intercept. On putting \(x=0\), we get \(y=c\), so the graph meets the y-axis at \(c\). In contrast, \(m\) represents the slope, not the y-intercept. Exam tip: set \(x=0\) to find the y-intercept.
