Please actually answer and don't just take the points.

Which lines are perpendicular to the line y – 1 = 1/3(x+2)? Check all that apply.

Please explain why, I would appreciate it

-y + 2 = –3(x – 4)

-y − 5 = 3(x + 11)

-y = -3x – 5/3

-y = 1/3x – 2

-3x + y = 7

What is the inverse of the function f(x)=4x+8

Will mark 50 show all what is the solution to the system of equations? use the substitution method and show your work. -5x+y= -3 -15 x+3y=7 explain what your answer in part (a) tells you about the association of the lines in this system.
