Answer:
4x + 3y = 0
Explanation:
A line perpendicular to one written in standard form can be found by swapping the x- and y-coefficients and negating one of them. Usually, you want the leading (x) coefficient to be positive, so here we can negate that one. This process give ...
4x + 3y = 0
The constant on the right can be chosen to make the line go through a desired point. Here, no point is specified, so we have set it to zero.
