What is the slope of the line (y=4-2x)?
Answer and explanation
Correct answer: -2
The slope-intercept form is (y=mx+c), where (m) is the slope. The given equation can be written as (y=-2x+4), so the coefficient of (x) is -2 and the slope is -2. Although 2 is the magnitude, the negative sign shows that the line falls from left to right. Exam tip: In (y=mx+c), take the complete signed coefficient of (x) as the slope.
