You can put this solution on YOUR website!
Write the equation for the following relation.
C = {( ,  ): ( ,  ), ( ,  ), ( ,  ), . . .}
we can first find a slope  using two given points (, ) and (, )
now use any of given points, substitute and , solve for 
.....if  and  , we have
so, your equation is: 
let check if all points lie in a line:
