Given:
The values of input and outputs are given
Output is increasing by 9 for the increase in x values.

Step-by-step explanation:
x -2 -1 2 7
y -6 -6 -2 3
All y are in under root
Answer:
constant of proportionality, k is 3
Step-by-step explanation:
constant, k= y/x
k=9/3
= 3

-4c - 11 = 4c +21 add 4c to both sides
</span>
<span>
-4c - 11 + 4c = 4c + 21 + 4c simplify
- 11 = 8c + 21</span> <span> subtract 21 from both sides
- 11 - 21 = 8c + 21 - 21 </span><span>simplify
- 32 = 8c divide both sides by 8
c = - 4That's it
