multiply both sides by 5 3(15k+10)=5(12k-9)
get rid of the brackets 45k+30=60k-45
take away 45k to both sides 30=15k-45
plus 45 to both sides 75=15k
divide both by 15 k=5

The following scatter plot shows the data for NCAA quarterbacks comparing their attempted passes to completed passes.

The line of the best fit is shown in the picture which is approximate near the dots.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

The slope and y-intercept can be found using the formula below:

$\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}$
