Okay, here we're asked to graph the following two inequalities.
00:03
We have x plus y is less than or equal to zero or 3x minus 6y is greater than or equal to 12.
00:16
Okay, so we'll start with the easier one of these two.
00:18
We'll do that in blue.
00:20
We're going to solve this inequality for y.
00:22
So we'll subtract x on both sides.
00:25
We'll get y is less than or equal to negative x.
00:28
So we know that's a solid boundary line that goes in a diagonal.
00:32
Direction like that.
00:38
Okay, we're going to shade everything under this line because y is less than this line.
00:44
Okay, we're shading all this region.
00:47
Let's do it very roughly here under that.
00:50
We'll do the second equation in red.
00:53
We need to solve this to get the y by itself...
