Question 404287: I have gone over this homework problem time and time again and cannot get the answer correct. Please show me how to do this correctly.
1. Find the intersecting point of the two straight lines: 2x-3y=5 and 3x+4y=1.
I converted the two equations to y=2/3x-5/3 and y=-3/4x+1/4 and found extremely large fractions for my answers. I finally came up with (1.3529,-0.7647)
2.The equation x=3 represents?
I said a verticle line because it cannot be a point on the x-axis. Is this correct?
