solve x and y?
i honestly have no idea this came directly from a review sheet.
To solve graphically, means graph each line and see where they intersect.

Ok, you have grid paper to draw?
you can graph by draw on grid paper, and solve x,y to check it correct
Do you want me to solve for x and y?
y=-x, you rewrite: y+x=0
y=x+2 , you rewrite: y-x=2
Add : y-x=2
x = 0
subtitution x=0 find y
you can check by use the grid paper graph 2 line if they intersect at (0,2) then you correct ,if not maybe the graph you draw it wrong or solve eqaution it wrong,I hope it help
sorry I tye wrong my keybroad not work propertly, equation not eqaution
Am I nuts?
Graphically, y=-x is a -45 degree line that crosses the axes at the origin (0,0)
and y=x+2 is a +45 degree line that crosses the Y axis at 2 (if x=0, y=2)
the two lines will cross at (-1,1)
