Using the equation 2x plus 3y equals 5, we need to replace some x values so that we can create some coordinate points so we can graph it on the graph.
00:11
So the first thing we're going to do is rearrange this to y equals mx plus b.
00:15
So we're going to subtract 2x from both sides.
00:19
So we get 3y is equal to negative 2x plus 5.
00:23
Divide everything by 3.
00:26
We get y is equal to negative 2 thirds x plus 5 thirds.
00:31
So that's what we're going to replace or use to figure out our y values with the given x values.
00:42
So we have y is equal to negative two -thirds.
00:47
Instead of x, we're going to replace it with negative 5 plus 5 thirds.
00:53
That reduces.
00:55
After we clean it up, that becomes 5.
01:02
So we get the coordinate negative 5, 5.
01:05
So we do the same thing with negative 2.
01:09
So y is equal to negative 2 thirds.
01:14
We have negative 2 instead of negative 5.
01:19
And when we plug that in, we get the coordinate point negative 2, 3.
01:26
Do the same thing for 1.
01:28
So y is equal to negative 2 thirds...
