What is the sign of the slope of the line (y=-10x+31)?
Answer and explanation
Correct answer: Negative
A line in the form \(y=mx+c\) has slope \(m\). Here, the coefficient of \(x\) is \(-10\), so the slope is \(-10\) and its sign is negative. A zero slope occurs only when \(m=0\). Exam tip: In \(y=mx+c\), check the coefficient of \(x\) to identify the sign of the slope quickly.
