Question 616901: If someone could help on this it would be greatly appreciated.
For the systems of linear equation
-Determine how many solutions exist
-Use either elimination or substitution to find the solutions
-Graph the two lines labeling the x intercepts, y intercepts, and points of intersection.
x + y = 3 and y = x + 3

Hi, 

x + y = 3 and 

y = x + 3  OR -x+y = 3



 x + y = 3      GREEN  (3,0) x-intercept  (0,3) y-intercept

-x + y = 3      BLUE   (-3,0) x-intercept  (0,3) y-intercept

    2y = 6

     y = 3  and x = 0  |||Note: (x+y=3)

Pt(0,3) is the Pt of Intersection
