Question 44047: slove each of the following systems by graphing.
2x-y=4
2x-y=6 Found 2 solutions by adamchapman, fractalier:Answer by adamchapman(301) (Show Source):
You can put this solution on YOUR website! Below I have graphed the two functions by rearranging each into the form "y=mx+c" where m is the gradient and c is the y-axis intercept.
The equations of the lines are:
y=2x-4 (red)
y=2x-6 (green)
I hope this helps
P.S. I am trying to start up my own homework help website. I would be extremely grateful if you would e-mail me some feedback on the help you received to adam.chapman@student.manchester.ac.uk
You can put this solution on YOUR website! If we rearrange
2x-y=4
2x-y=6
into
y = 2x - 4
y = 2x - 6
Both have a slope of 2...hence they are parallel and no solution exists...
The first one crosses the y-axis at (0, -4) and the second crosses at (0, -6).
