Let's rewrite the equation
9x+3y=0
3y=−9x
y=−3x
The slope of a line with equation
y=mx+c
is =m
Here, we have m=−3
The slope of the line m' perpendicular to another line is
m m = - 1
m = - 1 m = - 1 - 3 = 1 3

I have just started auditing Linear Algebra, and the first thing we learned was how to solve a system of linear equations by reducing it to row echelon form (or reduced row echelon form). I know how to solve a system of linear equations using determinants, and so the using row echelon form seems to be very inefficient and an easy way to make mistakes.
The lecturer seemed to indicate that this will be useful in the future for something else, but a friend who has a PhD in mathematics said it is totally useless.
Is this true? Is this technique totally useless or is there some "higher mathematics" field/ technique where row echelon form will be useful?
