The matrix that represents this system takes the x coordinates and puts them in a column and then the y coordinates and puts them in a column and then the solutions in another. Like this: ![\left[\begin{array}{ccc}7&8\\-3&9\\\end{array}\right] =\left[\begin{array}{ccc}28\\-24\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%268%5C%5C-3%269%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D28%5C%5C-24%5Cend%7Barray%7D%5Cright%5D%20%20)
. That's what your matrix would look like.
