Point slope form is
Y-y1=m(x-x1)
-in this^ u only should put number in the y1, m, and x1
-m is your slope
Slope intercept form is
Y=mx+b
-start out with putting numbers in m and b and then you'll find your way to your y and x
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:
the domain in general is negative Infinity, infinity.
Step-by-step explanation:
Infinity means it is a straight line that goes on forever it never stops. graph the -6 and 1. I am not totally sure what domain restrictions are if you have an equation for it go a head and put it there and I can help you more.
