In this problem, we want to find out if the coordinates 05 or the coordinates negative 1, negative 8, could be solutions to the equation y equals 3x minus 5.
00:16
In order to do this, we're going to take the x and y coordinates, which we're giving, and we're going to put them in place of the x and y in our equation.
00:26
And if we get a correct answer, then these will be a solution.
00:30
If they are not a correct answer, they cannot be a solution.
00:34
So let's start with our first set of 0, 5.
00:38
So our x coordinate is 0, and our y coordinate is 5.
00:43
So we're going to rewrite this equation with those correct coordinates.
00:48
So we're going to rewrite as 5 equals 3 times 0 minus 5.
00:56
So when i simplify, i'm going to have 5 equals 0 because 3 times 0.
01:01
0 minus 5 and 0 minus 5 is negative 5.
01:09
5 does not equal negative 5...
