I think it's C,But I'm not sure
"Linear function" means the highest degree of any term is 1.
Equation 1: degree is 2
Equation 2: degree is 2
Equation 3: degree is 1 . . . . this is your linear function

Here’s the answers hope this helps.
Choose whatever 2 points you want and you will always get the same slope. Calculate the rise and run.
Hoped this helped :)
