Question

How do I find slope of a line (0,3) and (8,-3)

Answer 1

Slope  = (y2 - y1) / (x2 - x1)
(0,3)....x1 = 0 and y1 = 3
(8,-3)...x2 = 8 and y2 = -3
now sub...pay close attention to ur signs
slope = (-3 - 3) / (8 - 0) = -6/8 = - 3/4 <==

Answer 2

Slope = (3 + 3)/(0 - 8)
slope = -6/8
slope = - 3/4
