Perpendicular lines have opposite and reciprocal slopes. This means that we take the original slope (2) and negate it (-2). Now that we have the negated version, we need to flip it (-1/2).
With the slope of our new equation decided, we simply need to plug it along with the point into point-slope base form and then solve for y.
