To find the slope you need to pick two points. Points (2,4) and (4,3) are the points I used. (It does not really matter what points you chose). Now we have to follow the formula to find the slope. The formula can be seen below
Slope (m) = ΔY/ΔX
Now solve
ΔX = 4 – 2 = 2
ΔY = 3 – 4 = -1
Once you have solved it, you take it and make it a fraction
