6x+8y = 12 8y = -6x+12 Divide all terms by 8:- y = -0.75x+1.5 which is now in slope intercept form
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2

Need to put in function form. Y =mX + c 6X + 8Y = 12 8Y = - 6X + 12 Y = - 3/4X + 3/2 ----------------------- read off function m = - 3/4 ---------------------slope

2y = 6x - 8y = 3x - 4========m(slope) = 3=========
5x+8y = 40 8y = -5x+40 y = -5/8x+5 in slope intercept form

6x plus 3y minus 2x plus 5y equals 4x plus 8y.
The answer depends on what the feasible region is and on what operator is between 6x and 8y.
