What is the slope of the line (y=13-5x)?
Answer and explanation
Correct answer: -5
The slope-intercept form of a line is y=mx+c, where the coefficient of x, m, is the slope. Here, y=13-5x can be written as y=-5x+13, so the slope is -5. The number 13 is the y-intercept, not the slope. Exam tip: To find the slope, identify the coefficient of x in the equation written as y=mx+c.
