First let's find the slope of the line through the points and


Note: is the first point . So this means that and .
Also, is the second point . So this means that and .


Start with the slope formula.


Plug in , , , and


Subtract from to get


Subtract from to get


Reduce


So the slope of the line that goes through the points and is


Now let's use the point slope formula:


Start with the point slope formula


Plug in , , and


Rewrite as


Rewrite as


Distribute


Multiply


Subtract 8 from both sides.


Combine like terms. note: If you need help with fractions, check out this solver.


So the equation that goes through the points and is
