2x + y =5
Plot 2 points:
Let x = 0, then y = 5
Let y = 0, then x = 5/2
----
Plot (0,5) and (5/2,0) and draw a line thru them.
=======================================================
x-y = 4
Plot 2 points:
Let x = 0, then y = -4
Let y = 0, then x = 4
-----
Plot (0,-4) and (4,0) and draw a line thru them.
----
{{{graph(400,400,-10,10,-10,10,-2x+5,x-4)}}}
