And if using a matrix is possible, use one please! If not it's okay! Thanks!

Ahh I hate matrices, but it's easier to use regression on a calculator. Get a TI 83 or higher

•plug in your x-points in L1 and your y-points in L2
•then put 2nd quit to exit out
• click STATs but scroll right to CALC
•click on 5 which is QuadReg
