    y=mx+b You have m(slope)= 3/7 And you have (x, y) (9,-2) x=9 and Y=-2 We need to find b. So we plug all this information in to the equation y=mx+b -2=(3/7)(9)+b Solve that and you will get b. Once you have b, plug it in to the equation, along with the slope.

    and ur point (9,-2) so let \[x _{1}=9 \] and \[y _{1}=-2\] and then plug ur values in the equation \[y=m(x-x _{1})+y _{1}\]

    actually it is y=(3/7)x-(41/7) or 7y=3x-41
