Which statement about the slopes of (y=4x-6) and (y=4x+9) is correct?
Answer and explanation
Correct answer: Both lines have slope 4
In the form y=mx+c, the coefficient m of x is the slope. Since the coefficient of x is 4 in both equations, both lines have slope 4 and are parallel. The values -6 and 9 are y-intercepts, not slopes. Exam tip: To find the slope, look for the coefficient of x.
