DR- Determine the Rule (Linear Function)
Look at the each input and output. Look for a consistent change. Test each change. Then write the linear function rule: Example:
x_|_5_|_14_|_-1_|_12_|_-10 y | -1 | 8 | -7 | 6 | -16 I checked and 14 - 6 = 8 and 12 - 6 = 6. So I think I have to subtract 6. Let me test the others: 5 - 6 = -1 Yes
-1 - 6 = -7 Yes
-10 - 6 = -16 Yes The rule is: y= x – 6
