A coordinate geometry question?
The straight line L has the equation 2y-x+7 = 0.
The straight line L2 passes through the point P(-1,6) and is perpendicular to L.
Find the equation of L2, giving your answer in the form ax+by+c=0

Slope of line L: 1/2
Perpendicular slope of L2: -2
Passing through: (-1, 6)
Perpendicular equation: 2x +y -4 = 0
