What is the sign of the slope of the line (y=-8x+25)?
Advertisement
Answer and explanation
Correct answer: Negative
In the form y=mx+c, the coefficient of x, m, is the slope. Here, m=-8, so the slope is negative. A zero slope occurs only for a horizontal line, whereas this line has slope -8. Exam tip: In y=mx+c, identify the slope by looking at the coefficient of x.
