You can put this solution on YOUR website! First lets find the slope through the points ( , ) and ( , )
 Start with the slope formula (note: ) is the first point (,) and ) is the second point (,))
 Plug in  , , , (these are the coordinates of given points)
 Subtract the terms in the numerator  to get  . Subtract the terms in the denominator  to get 
 Reduce
So the slope is
------------------------------------------------
Now let's use the point-slope formula to find the equation of the line:
------Point-Slope Formula------
 where  is the slope, and ) is one of the given points
So lets use the Point-Slope Formula to find the equation of the line
 Plug in , , and (these values are given)
 Distribute 
 Multiply and  to get 
 Add to both sides to isolate y
 Combine like terms and to get  (note: if you need help with combining fractions, check out this solver)
 Multiply both sides by 7 to clear the fractions
 Add 6x to both sides
