In this problem, we're given the equation y equals 2x squared.
00:06
And we're given two sets of coordinates.
00:09
And we want to know if either one, if not both of the sets of coordinates, could be solutions to our equation.
00:17
So in order to do this, we're going to plug in the coordinates in place of the x and y.
00:22
So in our first set of coordinates, 1 2, my x is 1, my y is 2.
00:29
So we're going to rewrite our equation with these numbers in place of x and y.
00:34
So i'll rewrite it as 2 equals 2 times 1 squared.
00:42
And remember, we're only square in the x.
00:44
So only the number we're putting in place of x will be squared.
00:49
So we have 2 equals 2 times 1 squared is 1, and 2 times 1 is 2...
