What is the slope of the line (y=-10x-3)?
Answer and explanation
Correct answer: -10
The slope-intercept form of a line is \(y=mx+c\), where \(m\) is the slope. In \(y=-10x-3\), the coefficient of \(x\) is \(-10\), so the slope is \(-10\). The value \(-3\) is the y-intercept, not the slope. Exam tip: in \(y=mx+c\), the coefficient of \(x\) is always the slope.
