Someone plz this is very confusing

A function is a special relationship where each input has a single output.

J {(4, -2), (5, -3), (4, -8), (5, -9)}

Input 4, output -2 and -8

Input 5, output -3 and -9

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
