All right, to solve these by graphing, i'm going to solve these equations by first turning them into y equals mx plus b form.
00:08
I'm going to do that because this is the slope and this is the y intercept.
00:12
That makes it easier for graphing.
00:14
So for the top equation, i'm going to start by subtracting 5x to the other side.
00:18
So it looks like this.
00:20
2y is equal to a negative 5x plus 7.
00:23
Then we can divide everything by 2.
00:27
So it's negative 5 halves x plus 7 halves.
00:31
For the second equation, we do the same thing with the negative 10x.
00:33
I'm going to add that to the other side.
00:35
So negative 4 y is equal to a positive 10x minus 14.
00:39
And now we divide everything by a negative 4.
00:43
So this turns into a positive y, 10 divided by a negative 4.
00:47
If i reduced size of fraction is negative 5 over 2x...
