## 9.3 Homework booklet questions : 3, 4, 5, 6

### 3.)

A) Complete the table of values.
T = time, V= volume of water in litres

20t = V

Example:

20t = V

20(3) = V

60 = V

#### B) Graph the ordered pairs.

#### C) Is it reasonable to have points between the ones on the graph? Explain.

Yes, because for example, if the hose were on for 2 minutes, 40 L of water would go through.

### 4)

#### A) Complete the table of values.

P = number of pages printed, C = cost in cents

15p = C

Examples:

15p = C

15(2) = C

30 = C

#### B) Graph the ordered pairs.

#### C) Is it reasonable to have points between the ones on the graph? Explain.

No, because you can't print pages partially.

### 5)

#### A) y = 3x - 1 when x = 5

3x - 1 = y

3(5) - 1 = y

15 - 1 = y

14 = y

#### B) y = 4x + 1 when x = -3

4x + 1 = y

4(-3) + 1 = y

(-12) + 1 = y

(-11) = y

#### C) y = - x when x = (-4)

0 - x = y

0 - (-4) = y

4 = y

### 6)

( -2, -1, 0, 1, 2 )

Great Job Gabbey!! I like how you made a picture for most answers. Next time you could add a link to a game or video explaining more about this topic.
