So in this problem, we have a graph, and i'm just going to sketch a little bit of a picture here so you can kind of see what's going on.
00:16
The first question, and we have this labeled as 3x plus y is equal to 3, and we're also labeled that this is 2 thirds x minus y is equal to negative 3.
00:29
The first question here is asking us, how many order pairs would satisfy the equation that lies on this piece? pink or red line here.
00:38
And the answer to that is infinite.
00:40
They're an infinite number of points on that line.
00:43
Some of the points that happen to be on that line, if you look at the picture carefully, would be negative 1 -603 -1 -0.
00:57
Those are three easy to define points on that line.
01:01
In question b, we're saying we're looking at the blue line.
01:04
It says how many points would satisfy that equation.
01:07
Again, it's infinite.
01:08
Every point that lies on that line and there's an infinite number of them, including decimals and fractions and all sorts of messy things like that, will make this true.
01:16
We can find three points that are easy to identify, like negative 50, is a point.
01:24
Negative 3 .1 is a point...
