Answer 1

• Tables A and B represent linear relationship

-------------------------

Table A

• x = 2, 3, 4, 5 Difference is 1
• y = 14, 21, 28, 35 Difference is 7

• This is linear and the slope is 7

Table B

• x = -2, -1, 0, 1 Difference is 1
• y = 10, 5, 0, -5 Difference is - 5

• This is linear and the slope is - 5

Table C

• x = 2, 3, 4, 5 Difference is 1
• y = 48, 72, 90, 114 Difference is inconsistent

• This is not linear
