With the formula: m=(y1-y2)/(x1-x2) you can sub in the values to get the slope (m).
m=(4-2)/(2-(-3))
= 2/5
Therefore the slope is 2/5.
To solve for the unit rate, know that the final answer must be out of 1. Or it is the quantity or amount of something per unit of measurement.
For instance in the above question, the unit rate for 32 teams in 4 divisions would be 8 teams per division.
Likewise for the other question it would be 270/15.
we have

Step 1
Eliminate the parenthesis

Step 2
Group terms that contain the same variable

Step 3
Combine like terms

therefore
the answer is
