If the line is (y=mx-8), what does (m) represent?
Answer and explanation
Correct answer: Slope
In the form y = mx + c, m represents the slope, that is, the change in y for a one-unit change in x. Therefore, in (y=mx-8), m is the slope. Here, -8 is the y-intercept; it shows where the line meets the y-axis. Exam tip: In y = mx + c, identify m as the slope and c as the y-intercept.
