This is parallel?
Y = -1/2x+4 and y =2x-2

no, it is perpendicular ... parallel means the two lines have the same slope (multiplier of x); perpendicular means the two slopes are negative inverse of each other (when multiplied together, the product is -1). Since -1/2 * 2 = -1, the two lines are perpendicular.
