Question 159914
Can you tell me how to graph y=-2x+3? And why it is graphed in such a way? 
----------------------------
Two points determine a line so find two points.
If x = 0, y = -2*0+3; y = 3
-------
If x = 1, y = -2*1+3; y = 1
---------
Plot the two points (0,3) and (1,1).  then draw a line thru them to see the graph.
-----------
{{{graph(400,300,-10,10,-10,10,-2x+3)}}}
