Find the slope of the line that passes through (2,1) (4,4)

To find the slope you have to subtract x sub 2 minus X sub 1 over y sub 2 minus y sub 1

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Agc and bgd are vertical angles
