In this project I have to bulid a model of the 3-D coordinate system and graph an equation with 3 variables. The equation my group choose is x+4y+2=4. The section I choose to do is (-x,y,z). Before graphing I have to change the equation to -x+4y+2z=4, then I find the intercepts. The intercepts are (-4,0,0), (0,1,0), and (0,0,2). I plot the 3 points on the (-x,y,z) section and connect it.
