In the line (y=3x-8), what are the slope and (y)-intercept?
Answer and explanation
Correct answer: Slope 3, y-intercept -8
The standard form of a line is \(y=mx+c\), where \(m\) is the slope and \(c\) is the y-intercept. In \(y=3x-8\), \(m=3\) and \(c=-8\); therefore, the slope is 3 and the y-intercept is -8. Option B incorrectly interchanges the slope and the intercept. Exam tip: identify the coefficient of \(x\) as the slope and the constant term as the y-intercept.
