So we have this equation, y equals 2x plus 1.
00:05
And we want to graph the equation by using two linear equations.
00:09
So the first step is to solve for when y equals the positive version of this, which is just why equals 2x plus 1, but also the negative of this.
00:19
So y equals negative of 2x plus 1.
00:22
And don't forget those parentheses because it's not just negative 2x, it's the negative version of the entire thing inside the absolute value.
00:31
So the first step is to simplify it, and this one's already simplified, but we can simplify this one further.
00:37
This becomes negative 2x minus 1 because we distribute that negative.
00:42
So now we need to graph this equation.
00:47
So i pull up a graph, and i always start with the y intercept...
