The first, yes
The second, yes
The third, no
The fourth, yes

$f (x) = 3 x - 7$ $f(x) = 3x - 7$

$f (2) = - 1; f (3) = 2; f (- 1) = - 10; f (1) = - 4$ $f(2) =-1 ; f(3) = 2 ; f(-1) = -10 ; f(1) = -4$

What is the solution set to the line 3x-y=73x−y=73x-y=7 from the set of (2,-1), (3, 2), (-1, 4), (1, -4)?
