Answer:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
Step-by-step explanation:
Given

Required
Create a table that represents this scenario
Because x represents time, x can not be negative. So, the domain of x is:

Assume 

Assume x = 4

Assume x = 6

Hence, the table is:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
6900 + 8100 = 15000
15000 divided by 2 = 7500
So your answer is 7500
4 6/9= 38/9
7 5/3= 26/3
3 7/8= 31/8
5 19/14 =89/14
Answer: y=4/3x-10
Step-by-step explanation: Find the equation using Point-Slope formula.
