Okay, for these equations, we want to solve them by graphing.
00:04
In order to do that, i'm going to rewrite them into y -equals mx plus b form, because m is going to be my slope, and b is my y intercept.
00:12
So for the first equation, i'm going to bring the 3x over, so that means i'm going to subtract it.
00:17
So that 5y is equal to a negative 3x plus 10.
00:21
And then i divide everything by 5.
00:24
So y equals a negative 3 over 5x plus 2.
00:29
The second equation is already in y equals mx plus b, so i just need to start plotting these lines then.
00:35
So this one, the first line crosses at a positive two, and it's got negative three -fifths -firt slope.
00:41
So crossing at positive two means it's crossing at zero -two.
00:44
And negative three -fifths -fifth slope is going to go up three, so one, two, three, up, and then one, two, three, four, five to the left.
00:51
And also go down three, and then one, two, three, four, five to the right.
00:57
So just make a nice straight line there.
01:02
That one missed a little bit, so i'll fix that.
01:05
That's better...
