Your answer is going to be option C.
I put your equation in the problem into slope-intercept to give me its slope. Then I took the reciprocal of this, because it wants a line perpendicular to the one in the orig. equation, for the new equation.
Then I plugged in the given ordered pair in slope-intercept form and solved for B. Plug that back in and, voila, you get option C as your answer.
