slope of (13,0) and (9,-4)
To find the slope of a line passing through two points, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (13, 0) and (9, -4):
x1 = 13, y1 = 0
x2 = 9, y2 = -4
m = (-4 - 0) / (9 - 13)
m = -4 / -4
m = 1
Therefore, the slope of the line passing through the points (13, 0) and (9, -4) is 1.
