What's the slope of (2, -9) and (4, -1) write your answer as a fraction.
The slope of the line passing through the points (2, -9) and (4, -1) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging the values in:
m = (-1 - (-9)) / (4 - 2)
m = (-1 + 9) / 2
m = 8 / 2
m = 4
So, the slope of the line passing through the points (2, -9) and (4, -1) is 4.
