Answer:

Step-by-step explanation:
Given





Required
Find the constant of variation
From the question, the variation is as follows



Convert variation to equation

Where k represents the constant of variation
Make k the subject of formula;
Multiply both sides by s * t


Divide both sides by p



Substitute the values of p, r, s and t in the above equation


Divide numerator and denominator by 6

Hence, the constant of variation is; 
Since the shading on the left side, and the line goes through the x axis, your answer would be B.
Answer:
- Domain:

- Range:

Step-by-step explanation:
<u>Domain</u>
The graph shows the points in which the domain is located. To find the Domain, go to the point in the x-axis (the horizontal line) and note the number where the point lies. For this question, the Domain lies in -5 and 1. Once you've found that, it's time to write it down. To do that you'll need to write the number at the most left before the one at the right. So it should be -5 less than/equal to X. Now since the point at the right is an "open-circle", x is less than the number at the most right. Not the same as a <u>closed circle.</u> So at the end of the process, you should have gotten -5 less than/equal to X less than 1 =
.
<u>Range</u>
The graph shows the points in which the range is located. To find the Range, go to the point in the y-axis (the vertical line) and note the number where the point lies. For this question, the Range lies in -4 and 7. Once you've found that, it's time to write it down. To do that you'll need to write the number at the most left before the one at the right. So it should be -4 less than/equal to X. Now since the point at the right is an "open-circle", x is less than the number at the most right. Not the same as a <u>closed circle.</u> So at the end of the process, you should have gotten -4 less than/equal to X less than 7 =
