So for this problem, we have x minus 2y equals 4.
00:07
And we have x squared minus y equals 0.
00:14
So you're given a choice, like you can choose to solve this algebraically or you can solve it graphically.
00:21
I chose graphically, mostly because these are relatively easy to solve for y.
00:27
And that way we can just investigate what it looks like.
00:31
Maybe draw a quick estimate.
00:32
So this first one, if we solve for y, we're going to subtract x from both sides, then divide by negative 2.
00:41
So it's just going to be one half x minus 2.
00:46
Our second equation, we're just going to subtract x squared and then divide by negative 1...
