Question

determine whether y varies directly with x if so find the constant of variation k
3y=-7x-18

Answer 1

Dear Student:

Given 3y=-7x-18

             y =-7/3-18/6

            y = -7/3-3

  Equation of Straight line

          y  = mx+k

 Where, m is slope here -7/3

              and k is constant here, k =-3

Yes, y varies directaly.

Because y proptional to x.

And k is -3

Hope it helps

Thanks

With Regards
