Answer and explanation
Correct answer: y-intercept
In the linear equation y=mx+c, putting x=0 gives y=c. Thus, c gives the point where the line crosses the y-axis, so it is the y-intercept. Here m is the slope, whereas the x-intercept is found by putting y=0. Exam tip: To find a y-intercept, always set x=0.
