Question 170807: 2.Plot the graph of the equations 4x-6y=2 and 2x-3y=1 and interpret the results.
4x-6y=2
-4x+6y=-2
0=0
These lines are the same and intersect at every point.
Y intercept:
2x-3y=1
2(0)-3y=1
0-3y/3=1/3 y intercept = (0,1/3)
Y=0: 2x-3(0)=1
2x/2-0=1/2 x intercept = (1/2,0)
4x-6y=2
X=0: 4(0)-6y=2
0-6y/6=2/6 = 1/3 y intercept = (0,1/3)
Y=0: 4x-6(0)=2
4x/4-0=2/4=1/2 x intercept = (1/2,0)
Could you please tell me if I did the above problem correctly and could you show me how to graph it.
