Answer:
-5
Step-by-step explanation:
To find the slope of the line passing through two points, you can use the formula:
Slope (m) = (y2 - y1) / (x2 - x1)
Let's calculate the slopes for the given pairs of points:
A. (5,4) and (-4,3):
- x1 = 5, y1 = 4
- x2 = -4, y2 = 3
Slope (m) = (3 - 4) / (-4 - 5)
Slope (m) = -1 / -9
Slope (m) = 1/9
Therefore, the slope of the line passing through points (5,4) and (-4,3) is 1/9.
B. (10,8) and (9,13):
- x1 = 10, y1 = 8
- x2 = 9, y2 = 13
Slope (m) = (13 - 8) / (9 - 10)
Slope (m) = 5 / -1
Slope (m) = -5
Therefore, the slope of the line passing through points (10,8) and (9,13) is -5.
