Just need to graph each line , on scale and read the (x,y) on scale. The answer should be same answer as the algebraic solution.

    y = X+2
    3x -y =10
                            to graph. Y= x+2
 
                           intercept points : ( 0,2) y intercept, (-2,0) X-intercept. Graph by connecting the intercept
                               points.
 
                            to graph 3x - y = 10  : Intercepts : (0, -10) ,and ( 10/3, 0). Graph by connecting
                            intercepts.
 
                Y = X+2
                3X -y = 10
 
                     Solution by algebraic method.
                      Substitute Y in first equation into 2nd.
 
                3X - X -2 = 10
 
                 2X - 2 = 10
 
                 2X = 12
                   
                  X = 6
                  Substitute X =6 into 1st equation:
                  Y =6+2 =8
 
                   Answer : ( 6, 8) . The intersection point should read from scale ( 6,8).
