Question 578060: I need to find the X and Y intercepts of the two equations. 4x-2y=6 and x-y/2=-1.5. I have already found the X and Y intercepts of each but now I need to find the "solution" to the problem. I'm very confused on how to find the solution. Here is what I have so far:
For equation 4x-2y=6
The X intercept is 3/2
The Y intercept is -3
For equation x-y/2=-1.5
The X intercept is -1.5
The Y intercept is 3
I'm also needing to graph these. I can graph them with no problems, it's just finding the "solution" that is throwing me off. I'm not quite sure what they mean by it.
