Answer:
6x6x6x6x6x6x6
Step-by-step explanation:
6^2 is 6x6
6^3 is 6x6x6
etc...
6^7 is 6x6x6x6x6x6x6
slope is 1/3
Explanation:

We apply the slope formula:


We have to determine if the functions are linear or not.
We can do this by rearranging the equations in this form:

where m and b are constants.
<em>NOTE: There are many ways to prove that a function is linear, but this is the easiest for this question. </em>
36.

As this function can not be written in the form y=mx+b, then it is not linear.
37.

This function is now in the form y=mx+b, where m=3/4 and b=-15. Then, this function is a linear function.
Answer:
36. Non-linear.
37. Linear.
7y - 3x = -5
-3x = -7y - 5
x = 7/3y + 5/3
