This problem deals with graphing two variable linear inequalities.
00:05
And we're going to start by finding the x and y intercept.
00:12
When you're calculating two variable inequalities, the easiest way to get your two points on a line will be to calculate the intercepts.
00:20
So for the x intercept, which means y is equal to zero.
00:24
Let's plug in a zero for y.
00:25
So we get 5x plus 10 times 0 is greater than 15, is what you're thinking, but we're determining a precise point.
00:35
So we're going to use equal to.
00:36
So this means 5x is equal to 15, because 10 times 0, 0, divide by 5, divide by 5.
00:42
We'll say x is equal to 3.
00:45
So let's say that point is right there.
00:47
X is equal to positive 3.
00:49
And then for the y intercept, for the y intercept, that means x is equal to 0.
00:56
We'll plug in 5 times 0 for x equals 0.
01:02
Plus 10y equals 15 because it's a precise point...
