Find the slope of the line passing through the points (-6, -9) and (4,-9)

To find the slope of the line passing through two points, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Plugging in the values of the points (-6, -9) and (4, -9):

m = (-9 - (-9)) / (4 - (-6))
m = 0 / 10
m = 0

Therefore, the slope of the line passing through the points (-6, -9) and (4, -9) is 0.
