Answer:
standard form of given equation is 5x - 8y = -3
Step-by-step explanation:

Standard form of linear equation is Ax + By = C
First we remove the denominator 8
We multiply the whole equation by 8
So equation becomes
8y = 5x + 3
Now we move 5x to the left hand side, we subtract 5x on both sides
-5x + 8y = 3
Now we remove the negative side from -5x by dividing the whole equation by -1
5x - 8y = -3
Matrices always go row x column.
Count the rows: 4
Count the columns: 3
The matrix is a 4 x 3 matrix
