What is the slope of the line (y=-9x+4)?
Advertisement
Answer and explanation
Correct answer: \(-9\)
A line in the form \(y=mx+c\) has slope \(m\). In \(y=-9x+4\), the coefficient of \(x\) is \(-9\), so the slope is \(-9\). The number \(4\) is the y-intercept, not the slope. Exam tip: In \(y=mx+c\), identify the coefficient of \(x\) to find the slope.
