A line passes through the points (1, 2) and (3, 1). What is the slope of the line? O
0-1
O2
0-2

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

Slope of the line using points

(1, 2) and (3, 1) is

Slope = 1-2/3-1 = -1/2

Equation of the line using point (1,2)

y - 2 = -1/2(x - 1)

y - 2 = -1/2x + 1/2

y = -1/2x + 1/2 + 2

y = -1/2x + 5/2
