    y + 2= -1/3(x - 9)

    First, put the equation of the line given into slope-intercept form by solving for y. You get y = 3x-5, so the slope is 3. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is -1/3. Plugging in the point given into the equation y = 1/3x + b and now solve for b

    the answer is y=-1/3*x+1

      I'm pretty sure an explanation of WHY this is the answer would almost be more beneficial than the actual answer.
