Answer 1

Similar example:

let's say the green line had a slope of 2/7. To find the perpendicular slope, you flip the fraction and the sign

flip the fraction: 2/7 -----> 7/2
flip the sign: +7/2 ----> -7/2

The original slope is 2/7 while the perpendicular slope is -7/2

Of course this isn't the answer as it's just a similar example.

Answer 2

So the answer of my problem would be -4/3?
