Given:
(-4, 2)
(5, 8)
x1 = -4
x2 = 5
y1= 2
y2 = 8
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 = (8 - 2)/(5 - (-4))
m = (8 - 2)/(5 + 4)
m = (6)/(9)
m = ⅔
Final answer:
The slope of the line = ⅔
