Gabbey's Algebra Scribepost

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 )

A) y = 4x + 1









B) y = -5x 








C) y = 3 - x
