What is the sign of the slope of the line (y=-6x+18)?
Answer and explanation
Correct answer: Negative
A line in the form y = mx + c has slope m, the coefficient of x. Here, m = -6, which is less than 0; therefore, the slope is negative. A zero slope would require the coefficient of x to be 0, as in y = 18. Exam tip: In y = mx + c, identify the slope by looking at the coefficient of x.
