Hi
solve the following system by graphing)finding were the lines intersect)
x-3y=9   OR y = (1/3)x - 3  Slope = 1/3 and y intercept is Pt(0,-3) Green
x+3y= -3 OR y = (-1/3)x - 1 Slope = -1/3 and y intercept is Pt(0,-1)Blue
Lines interscet at Pt(3,-2), this ordered pair is the solution for this system
CHECKING our Answer***
x-3y=9   
x+3y= -3
2x = 6,  x = 3 and y = -2  (y = (1/3)x - 3 )
