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

$m_{1} * m_{2} = -1$

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:

y = m*x + b , where m represents the slope.

$y = \frac{5}{4}x + 2$ $m=\frac{5}{4}$ $y = \frac{5}{4}x - \frac{5}{4} \\ m=\frac{5}{4} \\ m_{1}*m =\frac{25}{16}\\NotPerpendicular$ $y = -\frac{4}{5}x - 3\\ m=-\frac{4}{5}\\ m_{1}*m=-1\\Perpendicular$ $y =\frac{4}{5}x + 1\\m=\frac{4}{5}\\ m_{1}*m=1\\NotPerpendicular$ $y =\frac{4}{5}x + 2\\ m=\frac{4}{5}\\m_{1}*m=1\\NotPerpendicular$

choose all answers that are correct.

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