Given the points:
(3, -4) ( 9, -4)
x1 = 3
x2 = 9
y1= -4
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 - (-4))/(9 - 3)
m = ( - 4 + 4) / 6
m = 0 / 6
Having 0 in the numerator means the answer is undefined or does not exist, therefore the slope of the line does not exist since it lies on the same y-axis -4.
Final answer:
The slope of the line does not exist.
