Find the slope of the line passing through the points (2,5) and(8,-4) .
The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (2, 5) and (8, -4), we can substitute the values into the formula:
m = (-4 - 5) / (8 - 2)
m = (-9) / (6)
m = -3/2
Therefore, the slope of the line passing through the points (2, 5) and (8, -4) is -3/2.
