Given:
(-5, 2)
(-5, 4)
x1 = -5
x2 = -5
y1= 2
y2 = 4
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 - (-5))
m = (2)/(-5 + 5)
m = 2/0
We cannot have 0 in the denominator, since the answer will be undefined.
m = undefined
Final answer:
The slope of the line is undefined or does not exist.
