Question

Find the slope of the line that passes through the points  (1, -3) and (2, -1).

A) 1/2

B) -1/2

C) 2

D) -2

Answer 1

To find the slope, you must put the y values over x and then subtract.
-3-(-1) -2
---------- = --------- = 2
1-2 -1
The slope equals 2, so the answer must be C)2.

Answer 2

slope = (-1+3)/(2-1)
slope = 2
answer is C) 2
