Which line has slope (7)?
Answer and explanation
Correct answer: \(y=7x-6\)
In the equation \(y=mx+c\), the coefficient of \(x\), namely \(m\), is the slope. In \(y=7x-6\), the coefficient of \(x\) is 7, so its slope is 7. In \(y=x+7\), the slope is 1; 7 is only the y-intercept. Exam tip: identify the coefficient of \(x\), not the constant term, to find the slope.
