Which line has slope (5) and (y)-intercept (2)?
Answer and explanation
Correct answer: \(y=5x+2\)
The slope-intercept form of a line is \(y=mx+c\), where \(m\) is the slope and \(c\) is the \(y\)-intercept. Substituting \(m=5\) and \(c=2\) gives \(y=5x+2\). Therefore, option C is correct. Option B has slope 5, but its \(y\)-intercept is \(-2\). Exam tip: in \(y=mx+c\), the coefficient of \(x\) is the slope and the constant term is the \(y\)-intercept.
