Question 100852
ok first u need to find the gradient of the line connecting the 2 points. This is the change in y over the change in x {{{(y2-y1)/(x2-x1)}}}... doing this u get {{{(6-2)/(3-(-5))}}} = {{{1/2}}}.

using the formula {{{y-Y1=m(x-x2)}}} , where m is the gradient, and y1 and x1 are from the coordinate (3,6)

you get (using only one pair of coordinates)  {{{y-6=1/2(x-3)}}} 

which simplifies to give you: {{{2(y-6)=x-3}}}
This simplifies to give you: {{{2y=9+x}}}
