The slope formula is given as:
m = (y2 - y1) / (x2 - x1)
Plugging in the coordinates, we have:
m = (45 - 15) / (19 - 9)
m = 30 / 10
m = 3
Therefore, the slope of the line passing through the points (9, 15) and (19, 45) is 3.
Using the slope formula, find the slope of a line passing through the points (9, 15) and (19, 45) .
