Question

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

Answer 1

Finite Math. Find Any Equation Perpendicular to the Line 5x-4y=8. 5x−4y=8 5 x - 4 y = 8. Choose a point that the perpendicular line will pass through. (0,0) 0 , 0

Answer 2

Answer:

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.

• $y = \frac{5}{4}x + 2$ $m=\frac{5}{4}$

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