F (x) = 15x + 4

x = - 3: f (x) = 15x + 4

f (-3) = 15 (-3) + 4

f (-3) = - 45 + 4

f (-3) = - 41

(x, f (x)) = (-3, - 41)

x = 0: f (x) = 15x + 4

f (0) = 15 (0) + 4

f (0) = 0 + 4

f (0) = 4

(x, f (x)) = (0, 4)

x = 2: f (x) = 15x + 4

f (2) = 15 (2) + 4

f (2) = 30 + 4

f (2) = 34

(x, f (x)) = (2, 34)
