Question 198422: Solve graphically and check:
2x+y=10
x-y=2

You can put this solution on YOUR website! Solve graphically and check:
2x+y=10
x-y=2
----------------
Put both in slope intercept form:
y = -2x + 10
y = x - 2
-------------------------
Plot a couple of points for each one and draw a line thru each pair.
y = -2x +10
If x=0, y = 10 giving you point (0,10)
If x=1, y = 8 giving you point (1,8)
------------------------------
Y = x -2
If x = 0, y = -2 giving you point (0,-2)
If x = 1, y = -1 giving you point (1,-1)
-----------------------------------------------
--------------------------
Solution: (4,2)
-----------------------------
