The point is and the equation of line is .

The equation is in the form where m is slope and b is y - intercept.

Therefore slope of given line is .

Because the slopes of perpendicular lines are negative reciprocals, the slope of perpendicular line through is 2.

To find the y - intercept, substitute the values of in the slope - intercept from of equation and solve for b.

Subtract 4 from each side.

.

The y - intercept of perpendicular line is .
