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.
