Textbook 9.2: Patterns in a Table of Values (14, 16, 18) Scribepost.

The algebra post that contains the questions that may or may not turn your brain into mush.

14. b) Let f = Figures

Let s = Squares

 3f + 1.

14. c) 61 squares (20 x 3 + 1 = 61)

14. d) 30 squares

Figure 10: 10 x 3 + 1 = 31.

So: 61 - 31 = 30.

Let h = Height (m)

Let t = Temperature (C)

16. c) Since the h and t values are consistent, then yes, the ordered pairs are linear as the graph shows.

16. d) 1050 metres.

Let r = Rental Cost

Let p = People

18. c) r ÷ 5

Wow, that actually wasn't hard.

Also graph paper.
