Ok

You know, any help would be greatly appreciated, because I'm really getting pissed off.

I'm having word problems, u know, based on solving linear systems by graphing.

I'm having a problem that is kind of making me confused and lost.

So, I'll write down a system that I can't solve, instead of copying the whole word problem. Here it goes.

1) d = -55t + 3000 2)d= -40t + 2400

which is therefore,

1) y = -55x + 3000 2) y = -40x + 2400

I believe I need to find out the point of intersection, right? How do I do that? First, I'd need to use calculator, and type in both of these systems in "y=" button.

After I did that, I'd need to set the window right. And that's where my big problem is, that where I'm stuck, setting the window right. How the hell do I set the window right before finding out the point of intersection? That's where it's pissing me off........

Any input is greatly appreciated, because you know I will love you forever if you help me!
