Question

Dakarai wrote the system of linear equations below. 7x+8y=28 -3x+9y=-24 Dakarai then wrote the coefficient Matrix that represented this system. Which Matrix could she have written?

Answer 1

its a on edge

Explanation:

Answer 2

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]`. That's what your matrix would look like.
