Which lines are perpendicular to 5x + 4y = 8?

choose all answers that are correct.

_5x + 4y = _5
5y = _4x _ 15
5y = 4x + 5
_4x + 5y = 10

If two lines are penpendicular their slopes has to be reciprocal, satisfying the next condition:

Step-by-step explanation:

First of all we have to obtain the slope of each line, we can do this by reducing the line equation into this form:

, where m represents the slope.
