Answer:


See attachment for C and E
Explanation:
Given
--- Origin
--- distance of C to O
Solving (a): Plot point C
Calculate the coordinates of C using distance formula:

Where:
---

--


So, we have:


Square both sides


For this solution, we assume y = 0


Solve for x

So, the coordinates of C is: (1,0)

Solving (b): Plot point E
We have that E is 4/5 closer to the origin.
This implies that, the ratio is:

Multiply by 5

So, E is at 4:1 between O and C
Calculate the coordinates of E using:

Where
---
