What is the slope of the line (y=4x+3)?
Advertisement
Answer and explanation
Correct answer: 4
In the form \(y=mx+c\), the coefficient of \(x\), namely \(m\), is the slope. Here, in \(y=4x+3\), \(m=4\), so the slope is 4. The number 3 is the \(y\)-intercept, not the slope. Exam tip: identify the coefficient of \(x\) to find the slope.
