So number 52, we're given the inequality minus x minus y is less than three.
00:07
Total sketch a graph.
00:08
So first step is to get our y on its own, to put this into slope and this form.
00:14
So we'll add x to both sides and get minus y is less than x plus three.
00:21
And now to get rid of this negative sign, we'll multiply both sides of inequality by minus one.
00:25
Make sure you switch your sign.
00:27
Since you're doing, since you're multiplying both sides by a negative.
00:31
Y is greater than minus x minus three so now i can see that our graph so we can see that our y intercept is going to be at minus three two three and our slope is going to be negative one so we'll go up one and then one to the left we're going to connect our dots here make a dash line i'm going to start by making a solid line and then erasing bits out of it there we go there we go now we will to determine which side is going to have our shading.
01:13
We're going to pick a test point and plug it into our inequality.
01:17
If it is a solution, we'll shade that side...
