Answer:
1 and 3 are both perpendicular to segment NY
Step-by-step explanation:
1. Find the slope of line NY
slope of NY = 5-(-7)/-11-5 = - 3/4
Any line that is perpendicular to NY should have a slope of the inverse of negative slope of NY.
2.Find the slope of perpendicular lines
the inverse of negative slope of NY = - (-4/3) = 4/3
You slowly go down the bottom row and multiply each digit by the top row.

![0=x^{2}-18x+90](https://tex.z-dn.net/?f=0%3Dx%5E%7B2%7D-18x%2B90)
![x=9+3i or 9-3i](https://tex.z-dn.net/?f=x%3D9%2B3i%20%20%20or%20%20%209-3i)
Step-by-step explanation:
you need to use quadratic formula and you will find square root a negative ( -9 ), which is an imaginary no.
square root (-9) = 3i
