Question 1016236: Hello,
I am trying to write the slope intercept form of an equation. I figured the equation out, but it's supposed to be perpendicular to an equation already given to me. I took the slope (-1 over 6) from the equation and the two given points it gave me (3, -5). I plugged it in with point slope form and got y= -1/6x - 4.5. But I don't understand how it's perpendicular.
