Which statement about (y=-5x+14) and (y=-5x-4) is correct?
Answer and explanation
Correct answer: The slopes are the same and the y-intercepts are different
In the form y = mx + c, m is the slope and c is the y-intercept. The coefficient of x is -5 in both equations, so their slopes are the same. Their y-intercepts are 14 and -4 respectively, so they are different. Lines with equal slopes and different y-intercepts are parallel. Exam tip: identify the coefficient of x for slope and the constant term for the y-intercept.
