The slope of the points is -1/3
Answer:

Step-by-step explanation:
If we are to write an equation of the form
, then the function is linear; therefore, it has a constant slope
.
The slope
of the function is given by


thus we have

Now we find
from the fact that the first month of service costs $72.99, which gives us
, or


Substituting the values of
and
, we get our equation in the final form:

Answer:
5 3/8
Step-by-step explanation:
43/8
8 goes into 43 5 times with 3 left over so your answer will be
<h3>
= 5 3/8</h3>
So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.
I hope I helped!
