Use slopes to determine if the lines y= -x/3- 9 and 6x – 2y = -5 are perpendicular.

Only need to know if they are perpendicular or not!

Respuesta :

Answer:

They are perpendicular.

Step-by-step explanation:

When we convert the equation 6x-2y=-5 into y=mx+b form, it changes into y=3x-5/2. Since we know that perpendicular slopes are opposite reciprocal, the opposite reciprocal of -x/3 is 3. So, we know that these 2 slopes are perpendicular.
