To find the slope, you must choose two points on the graph that you could use to compare the vertical change (the rise) to the horizontal change (the run).
We can use points (4, 1) and (7, 5) and plug these values into the slope formula.
Let (x1, y1) = (4, 1) (x2, y2) = (7, 5)
Use the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (5 - 1)/(7 - 4) m = 4/3
Therefore, the slope of the line is 4/3.
