Find the slope of the line passing through the points (-7,-4) and (8,8) .
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the values from the two points:
m = (8 - (-4)) / (8 - (-7))
m = (8 + 4) / (8 + 7)
m = 12 / 15
m = 4 / 5
Therefore, the slope of the line passing through the points (-7,-4) and (8,8) is 4/5.
