Question

Which of the following sets of points forms a linear function?
A. (0, 5) (1, 8) ( 2, 11) (3, 14)
B. (1, 2) (2, 4) (3, 8) (4, 16)
C. (-2, 5) (-1, 2) (0, 1) (1, 2)
D. (-4, 8) (-3, 3) (-2, 0) (1, 3)

Answer 1

A. x=0, y=a*0+b=5, b=5
     x=1, y=a*1+5=8, a=8-5, a=3
     x=2, y=2*3+5=11
      x=3, y=3*3+5=14

A is the answer
