-x = x + 9
2 x = -9
x = -9/2
y = 9/2
two points on first line
(0, 0 ) and (1,-1)
two points on second line
(0,9) and ( 2 , 11)
draw the two lines and see where they cross (One has 45 deg slope, the other -45 deg slope)
Solve the following system of equation using the graphing method.
Y = negative X
Y = X + 9
