Given the points:
(6, -7)
(4, -8)
x1= 6
x2 = 4
y1 = -7
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 - (-7))/(4- 6)
m = (-8 + 7)/(-2)
m = (-1)/(22)
m =- ½
Final answer:
The slope of the line = -½
