Answer:
1
Step-by-step explanation:
First we take the two points (-7,5) and (-5,9).
Compute the slope:

Then the linear relation may be in the following form

Since the point (-7,5) is on the line, then

The relation is then

.
We check that the other point are on the above line:

W
e have then a linear relation.
Answer:
This is because exponents increase a number, for example
<em>squaring a number is basically multiplying it by itself.</em> So
. Now obiviously 4 is greater than 2. But lets make the numbers like this:

And again, 
Now, which is bigger 
A quarter is smaller than a half right?
So in this case we can see that fractions raised to an exponent get smaller while numbers raised to an exponent get bigger.
