Given:
(3, 4)
(1, 2)
x1 = 3
x2 = 1
y1= 4
y2 = 2
Find the slope of the line.
Formula for the slope of the line:
m = change in y/ change in x
m = (y2 - y1)/(x2 - x1)
Solution:
Substitute the given values to the formula for the slope of the line.
m = (y2 - y1)/(x2 - x1)
m = (2 - 4)/(1 - 3)
m = (-2)/(-2)
m = 2/2
m = 1
Final answer:
The slope of the line = 1
