Please help with the following question.
Abcd is a rectangle. Ab has equation x-2y+2=0 and c is the point (1,4).
1. Find the equations of cd and bc
2. Find the coordinates of the point b.
Any help with this would be greatly appreciated.

y = 1/2 x + 1
The line cd is parallel to the line Ab so the gradients are equaled:
SO for line cd we have y = 1/2 x + c.. now we substitute (1,4)
4 = 1/2(1)+c --> c= 7/2. --> y = 1/2 x + 7/2...
For line bc the line intersects at a right angle use this property to find the equation....
