What is the slope of the line (y=11-4x)?
Advertisement
Answer and explanation
Correct answer: -4
Write the line in slope-intercept form: \(y=-4x+11\). In \(y=mx+c\), the coefficient of \(x\), namely \(m\), is the slope. Therefore, the slope is \(-4\). Here, 11 is the y-intercept, not the slope. Exam tip: In \(y=a+bx\), the coefficient \(b\) of \(x\) is the slope.
