What is the slope of the line (y=-7x+1)?
Advertisement
Answer and explanation
Correct answer: -7
The slope-intercept form of a line is y=mx+c, where the coefficient of x, m, is the slope. In y=-7x+1, m=-7, so the slope is -7. The number 1 is the y-intercept, not the slope. Exam tip: In y=mx+c, identify the number multiplying x to find the slope.
