The linear equation that represents the <u>number of tiles in figure x</u> is given by:

---------------------
A linear equation has the format:

In which:
- m is the slope, that is, the rate of change.
- b is the y-intercept, that is, the value of y when x = 0.
---------------------
- Figure 0 has 5 tiles, that is, when
, thus 
- Seven new tiles in each figure, that is, a rate of change of 7, thus

The number of tiles in figure x is given by:

Answer:
timetaken to produce a playdough =4hours
a batch of playdough is produced in =1/6 hour
in 1hour,it will take 6 multiplied by a batch of playdough=6 batches of playdough to be produced
4 hours of making playdough in a day will produce=4 multiplied by 6 batches of playdough=24 batches of playdough in a day
It is a function because the input does not repeat itself.
