Question

What is the slope of the line that passes through the points (2, 8) and (6, 12)?

A.
–5

B.
–1

C.
1

D.
5

Answer 1

slope = (y2 - y1) / (x2 - x1)
set 1 : (2,8)....x1 = 2 and y1 = 8
set 2 : (6,12)...x2 = 6 and y2 = 12
now we sub
slope = (12 - 8) / (6 - 2) = 4/4 = 1 <===

Answer 2

the slope of the line is positive 1
