### Example Question #1 : Use Matrices To Represent And Manipulate Data: Ccss.Math.Content.Hsn Vm.C.6

Which of the following matrices represents the equations, , and ?

**Possible Answers:**

**Correct answer:**

To do this problem, all we need to do is put the coefficients for each variable into a matrix. The first column will be x values, 2nd column will be y values, and 3rd column will be what the equations are equal to.

It will look like this

where , are coefficients of and in the first and second equation respectively. refer to what the equations are equal to. So after placing the coefficients and what the equations are equal to in a matrix, it will look like the following.
