Question

Please help!
Line AB contains points A (−1, 3) and B (5, 3). Line AB has a slope that is

zero

undefined

positive

negative

Answer 1

to find the slope, use the slope formula : slope = (y2 - y1) / (x2 - x1)
(-1,3) x1 = -1 and y1 = 3
(5,3) x2 = 5 and y2 = 3
now we sub
slope = (3 - 3) / (5 - 1)
slope = 0/4

ok...remember this...when the 0 is in the numerator, it is a zero slope.It is also a horizontal line. If the 0 would have been in the denominator, it would have been an undefined slope and would have been a vertical line.
