Question

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

Answer 1

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

Answer 2

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.
