Which statement about (y=-6x+2) and (y=-6x-7) is correct?
Answer and explanation
Correct answer: Slopes are the same and y-intercepts are different
In the form y=mx+c, m is the slope and c is the y-intercept. Both equations have -6 as the coefficient of x, so their slopes are the same. Their y-intercepts are 2 and -7 respectively, so they are different. Option D is wrong because -6 is a negative slope. Exam tip: In y=mx+c, the coefficient of x gives the slope and the constant term gives the y-intercept.
