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:
