Question 89900
I solved and got y= -2x + 4 is this part correct? Next I do not know for sure how you graph this could you please explain it to me? 
----------
That equation is correct.
Plot at least two points to graph the equation:
If x=0, y=4
If x=1, y=2
If x=2, y=0
-------------
Plot these and draw a line thru them to get the graph.
{{{graph(400,300,-10,10,-10,10,-2x+4)}}}
