What are the slope and (y)-intercept of the line (y=3x+8)?
Answer and explanation
Correct answer: Slope \(3\) and \(y\)-intercept \(8\)
The slope-intercept 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 \(c=8\), so option A is correct. Option B incorrectly interchanges the coefficient of \(x\) and the constant term. Exam tip: the coefficient of \(x\) gives the slope, while the constant term gives the \(y\)-intercept.
