If: 11x+13y = 17
Then: 11/17x +13/17y = 1 by dividing all terms by 17
So: 11/17*17/22+13/17*17/26 = 1 because 1/2+1/2 = 1
Therefore: x = 17/22 and y = 17/26
Check: 11(17/22) + 13(17/26) = 17
Check: 11(17/22) times 13(17/26) = 72.25

What are the values of a and b when y plus 4x equals 11 is the perpendicular bisector of the line joining a 2 to 6 b showing workings?
They must be equidistant from the point of bisection which is their midpoint and works out that a = -2 and b = 4 Sketching the equations on the Cartesian plane will also help you in determining their values
