The slope is of $13, which means that each new sign costs $13.
-----------------
A linear function has the following format:
In which
- m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
- b is the y-intercept.
-----------------
- In the linear function in this problem, we have two points (x,y): (5,72) and (15,202).
- The slope is given by the <u>change in y divided by the change in x</u>, thus:
- The slope is of $13, which means that each new sign costs $13.

Answer:
25 times
Step-by-step explanation:
Scale factor is the ratio of dimensions of the image and the preimage.
Scale factor =
Since area of a figure is the square of dimensions.
Area = Length × Width
Therefore, area scale factor will be the ratio of square of the dimensions of image and preimage.
Area scale factor =
= (Scale factor)²
= 5²
= 25
Therefore, area of the image will be 25 times the area of the preimage.
To make this a fraction, let's put 
. We can divide both top and bottom by 6, leaving us with 
. This is as far as we can reduce it, making it your answer. I hope this helps!
