x + y = 6 / − x y = − x + 6 f or x = 0 → y = − 0 + 6 = 6 → ( 0 ; 6 ) f or x = 6 → y = − 6 + 6 = 0 → ( 6 ; 0 )
function form being slope-intercept?
y=-x+6
The equation x + y = 6 can be rewritten in function form as y = 6 − x or x = 6 − y . This allows either variable to be expressed in terms of the other. You can choose the form that is most useful for your situation.
