Answer:
The set U includes all positive integers from 1 to 20.
a)
<u>x is subset U and 14 < x ≤ 23, then x is:</u>
- x = {15, 16, 17, 18, 19, 20}
b)
<u>x is subset U and includes multiples of 4, so x is:</u>

Then, apply the fractions formula for division.

Then, simplify.

ANSWER:
m = -3/4
b = -3

STEP-BY-STEP EXPLANATION:
We have that the equation in its slope-intercept form is the following:

We calculate the slope as follows:

To calculate the slope we use the intercepts that are (-4, 0) and (0, -3), we replace:

Now, the value of b would be -3, since the y-intercept is (0,-3), therefore, the equation would be:
