So rastograft the inequality 0 .5x plus 1 .2y is less than 6.
00:05
I don't really like all these decimals that are here.
00:07
So what i'm going to do is multiply the whole inequality times the number that's going to get rid of the decimals.
00:13
I think the easiest number is just the number 10.
00:17
If we multiply everything by 10, it's for sure going to get rid of the decimals.
00:20
So 0 .5 times 10 is 5, and 1 .2 times 10 is 12, and 6 times 10 is 60.
00:30
So now i have no decimals left in my inequality.
00:34
And i want to rearrange these so that they're in the form, y equals mx plus b.
00:42
So let's take this 5x and let's flip that over here, subtract 5 from both sites.
00:48
12 y is by itself, negative 5x, positive 60.
00:53
And now i'm going to divide both sides by 12.
00:57
Everything's going to divide by 12.
00:59
12 and 12 cancel out.
01:01
Now my y is by itself.
01:02
Negative 5 and 12, they don't divide evenly, so i'm just going to leave them as a fraction, negative 5 over 12x, and 60 divided by 12 is 5.
01:13
So i'm going to plot the point 5 first.
01:15
That's my y intercept...
