What is the (y)-intercept of the line \(y=-\frac{3}{8}x+5\)?
Advertisement
Answer and explanation
Correct answer: \(5\)
In the form \(y=mx+c\), \(c\) is the y-intercept. Here, \(c=5\), so the line crosses the y-axis at \((0,5)\), and its y-intercept is \(5\). \(-\frac{3}{8}\) is the slope, not the y-intercept. Exam tip: put \(x=0\) to find the y-intercept.
