Explanation / Answer

Range would be considered (y) in this function. So, lets rewrite your equation. 28x+7y=56, moving the x to the other side and divide both sides by 7. 28x+7y=56 -> 7y=-28x+56 -> y=-4x+8 So, now we have an easy equation for which we will plugin the different domain's (or x values). 1. x=-8 y=-4(-8) +8 = 40; y=40 2. x=6 y=-4(6)+8 = -16; y=-16 3. x=-1 y=-4(-1)+8 = 12; y=12 So, the Range of this would be (40,-16,12), or if they want it as (domain,range), the answer would be: (-8,40), (6,-16),(-1,12).
