Question

Find the slope of the line that passes through the points (5, 8) and (9, 4).
A. 3
B. 1
C. -1
D. four-thirds

Answer 1

you will have to use the slope formula
slope = (y2 - y1) / (x2 - x1)
(5,8) x1 = 5 and y1 = 8
(9,4) x2 = 9 and y2 = 4
now we sub
slope = (4 - 8) / (9 - 5)
slope = -4/4
slope = -1
