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
to graph 3x - y = 10 : Intercepts : (0, -10) ,and ( 10/3, 0). Graph by connecting
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).
