**9.**

**a)**The patterns are:

The x axis begins at 0 increases by 1

The y axis begins at 2 increases by 2

To get the x value to the y value you have to go by the equation 3

*x*+2=y

**b)**

**c)**3

*x*+ 2 =

*y*

3(2) + 2 =

*y*

6 + 2 =

*y*

*8 = y*

**d)**3

*x*+ 2 =

*y*

3(5) + 2 =

*y*

15 + 2 =

*y*

17 =

*y*

**13.**

**a)**

*d*represents the distance in kilometres and

*t*represents time in hour.

**b)**15 represents the speed travelled by the cyclist.

**c)**

**d)**

**e)**Yes because the cyclist can travel for just a portion of an hour.

**f)**

*t*15 =

*d*

*(8)15 =*

*d*

120 =

*d*

**6.**

*s*= -4

*t*+ 2

*s*= -4(-1) + 2

*s*= +4 + 2

*s*= 6

10.

**a)**

**b)**

**c)**Yes the relationship is linear because the points on the graph lie in a straight line.
