Which line has slope (6)?
Answer and explanation
Correct answer: \(y=6x-4\)
In the equation of a line \(y=mx+c\), the coefficient of \(x\), namely \(m\), is the slope. In \(y=6x-4\), the coefficient of \(x\) is 6, so its slope is 6. The slope of \(y=x+6\) is 1 because the coefficient of \(x\) is 1. Exam tip: identify the slope from the coefficient of \(x\), not from the constant term.
