So I stayed home from school today because I owe two assignments and I really need to get them done. I can't ask my teacher for help on them because she'll say its not her job to teach me 9th grade material that I forgot.

I forgot how to solve systems of equations and I don't have a graphing calculator.
The directions are to solve every system of equation graphically and algerbraically. If someone could explain how to do it I might be able to understand. I googled it and I couldn't find anything helpful.

To show our work, we have the table with the three colums with x on the left, equation in the middle and y on the end.

Here's number 1:

y = x^2 - 4
y + x^2 = 4

Thanks to anyone who helps.
