Plot the solution for 5x plus y equals 10.
00:04
So here on the right side we have our equation, and i'd like to change that to the y equals mx plus b form.
00:11
In order to do that, we just need to subtract 5x on the left side and 5x on the right side, allowing us to cancel that 5.
00:21
And we have our equation as y equals negative 5x plus 10.
00:30
This allows us to easily substitute x to get the value for y.
00:37
So if we had x as negative 2, negative 1, 0 ,1, 2, we just plug in our x values here to get a y.
00:49
So for the first one, it's going to be negative 2 times negative 5, giving us a positive 10.
00:56
So we get 20.
00:59
Negative 1 times negative 5 gives us a 5 gives us a 15.
01:05
0 allows us to have 10.
01:07
1 gives us 5 and negative 2 times, sorry 2 times negative 5 is negative 10 plus 10 is going to get a 0.
01:16
So now we have an ordered pairs that we can use to plot out our solution.
01:24
Okay? this is going to be 0, 10, 15.
01:30
And two, zero.
01:33
So looking at our map, i did increments of five just so that it can fit on our video, but i would suggest that you do increments of one or two so that you have a more accurate diagram.
01:50
But this should be sufficient because we're just trying to show you that there's a way to find a solution by using a table in, by plying out the line.
02:02
Okay, so negative 220 is going to 2 .5 is this middle point right here, right? so we just want to be a little bit to the right of that.
02:13
So that's going to be right here.
02:15
And then we also have negative one.
02:17
So negative one is closer to the y axis...
