Answer:

Step-by-step explanation:

Put the equation in the form ax+by+c=0:

y\sqrt{3} =8x+\sqrt{3} \\=>8x-\sqrt{3} y+\sqrt{3} =0

Check the solutions:

(0,-1):

8(0)-\sqrt{3} (-1)+\sqrt{3} =2\sqrt{3}

So this is not a solution.

((\sqrt{3} ,9):

8\sqrt{3} -9\sqrt{3} +\sqrt{3} =0

So this is a solution
