A tile pattern has five tiles in Figure 0 and adds seven tiles in each new figure. Write a linear equation that represents this

Olenka [21]

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

$y = 7x + 5$

---------------------

A linear equation has the format:

$y = mx + b$

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 $x = 0, y = 5$ , thus $b = 5$
Seven new tiles in each figure, that is, a rate of change of 7, thus $m = 7$

The number of tiles in figure x is given by:

$y = 7x + 5$
