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 1 from both sides.
Combine like terms.
So the equation that goes through the points and is
