Question

Does the data in each table represent a linear function? If so, write the function rule?

1. x = 0, 1, 2, 3, 4
y = 2, 5, 8, 11, 14

2. x = 0, 1, 2, 3, 4
y = 0, 2, 5, 2, 0

3. x = -2, 0, 4, 6, 8
y = -1, -3, -7, -9, -11

4. x = -3, -2, -1, 0, 1
y = -1, 1, 2, 2, 2

Answer 1

The first one bc x goes up by 1 and y goes up by 3
