In this problem, we are going to determine if each point is a solution to the equation.
00:08
So our first x, x, y ordered pair is 0, negative 4.
00:15
And we want to see if that is a solution to y equals x minus 4.
00:19
So we're going to substitute our 0 in for our x and their negative 4 in for y.
00:30
And see if that makes a true statement.
00:32
Does negative 4 equal 0 minus 4? yes, it does.
00:38
So is 0 negative 4 a solution to that equation? yes.
00:42
If we graph this equation, would 0 negative 4 be on the line on the graph? yes, it would.
00:49
If it's a solution, it is on the line.
00:54
Okay? next, we'll check 3 negative 1...
