Question 613066
x+y=6
x-y=4
How do I solve this system so I can graph it
----
You only need 2 points to graph a line.
----
x + y = 6
Let x = 0, then y = 6, giving you (0,6)
Let y = 9, then x = 6, giving you (6,0)
Plot those 2 points and draw a line thru them:
{{{graph(400,400,-10,10,-10,10,-x+6)}}}
============================================
x-y = 4
Let x = 0, then y = -4, giving you (0,-4)
Let y = 0, then x = 4, giving you (4,0)
Plot those and draw a line.
{{{graph(400,400,-10,10,-10,10,x-4)}}}
