What is the slope of the line (y=8-2x)?
Answer and explanation
Correct answer: \(-2\)
The slope-intercept form of a line is \(y=mx+c\), where \(m\) is the slope. Writing the given equation as \(y=-2x+8\), the coefficient of \(x\) is \(-2\). Hence, the slope is \(-2\). Option 2 misses the negative sign, so it is not correct. Exam tip: Always check the sign of the coefficient of \(x\) while finding the slope.
