==================================================
Explanation:
Subtract the y coordinates: 9-3 = 6
Subtract the x coordinates in the same order: 10-5 = 5
Divide the differences:
slope = rise/run = (change in y)/(change in x) = 6/5
-------------------
You could also use the slope formula
m = (y2-y1)/(x2-x1)
m = (9-3)/(10-5)
m = 6/5
