Given:
(2.1, -4.2)
(2.5, .5)
x1 = 2.1
x2 = 2.5
y1= -4.2
y2 = -5
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 = (-4.2 - (-5))/(2.5 - 2.1)
m = (-4.2 + 5)/(0.4)
m = (0.8)/(0.4)
m = 2
Final answer:
The slope of the line = 2
