Answer:

Explanation:
To find the slope take any two convenient x, y value combo.
Find the difference between the two y-values(we call it rise).
Find the difference in the corresponding x-values (we call this the run)

Take points (3, 1) and (6,3). I could choose any two points but working with positive numbers makes it easier
Rise = 3- 1 = 2
Run = 6 - 3 = 3

Just for the heck of it let's take two other points to make sure we haven't goofed
Take points (-1, - 5/3) and (1, -1/3)
rise = -1/3 - (-5/3) = -1/3 + 5/3 = 4/3
run = 1 - (-1) = 2
rise over run = 4/3 ÷ 2 = 4/3 x 1/2 = 2/3
