In this problem, we're being asked to solve this equation using our graphing calculator.
00:04
So we're going to graph this.
00:06
So if you go to your y -equals menu, in your first equation, y -sub -1, you're going to enter in the left -hand side of our equation.
00:13
So you're going to do three parentheses, x plus two, close -preemphasies, minus 5x.
00:18
Then scroll down to 1 to the y -sub -2 equation, and then you're going to type in the right -hand side, 3x minus 4.
00:25
Now you can go ahead and graph it.
00:27
And if you're in your standard 10 by 10 viewing window, you'll notice that the two graphs cross in that first quadrant.
00:34
So now we need to see where they cross.
00:36
So to do this, you're going to type in the second or type the second button and then the trace button, which is right next to graph.
00:43
And then you're going to choose choice number five, which says intersect...
