helppppppppp

Answer 1

12) The function is linear.

13) This function is not linear.

Explanation:

13) A linear functions equation must be in y = mx + b form

When you graph the table there is no y = mx + b equation that makes a line that passes through all the points.

Answer 2

• A linear function follows a constant rate of change
• Here we see x moves by 4 units and that y decreases by 4 units then suddenly changes to 6 units hence 13 Is Not A function
• For 12, it is a function because it follows a consistent rate of change which is x or one unit of change.
