What is the equation of the line that is perpendicular to the line y = 1/2 x + 7 and passes through the point (6, 2)

the answer is C, y=-2x+14.
perpendicular lines are always the negative reciprocal of the original slope, and the y intercept is 14 because if you plug the x and y (6,2) into the equation y=-2x+b, you get b=14, b being the y intercept
