Okay.

Answer 6

(2,4) in A gives 2 + 4(2) = 2+8 = 10

Answer 7

Wouldnt that be C then?

Answer 8

or B?

Answer 9

Not C

Answer 10

try B

8 + 2(0) = 8 - the first one fits

now try (6,1) and (4,2)

Answer 11

(6,1) means x=6 and y=1

Answer 12

Oh that makes so much more sense lol.

Answer 13

so its B

Answer 14

so 6 + 2(1) = /
