Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) Find f(0)
we know that
Looking at the data in the table
When the value of x increases by 1 unit, the value of y increases by 3 units
therefore
When the value of x decreases by 1 unit from 1 to 0, the value of y would decreases 3 units from 5 to 2
thus

This value represent the y-intercept
Part 2) Find the equation of the given linear
Find the slope
take the points (1,5) and (2,8)

The equation of the line in slope intercept form is equal to

we have

substitute

Answer: a=2/5b + 1/5c (I may have answered your question but idk if I did)
Step 1: Add -4a to both sides.
9a−2b+−4a=4a+c+−4a
5a−2b=c
Step 2: Add 2b to both sides.
5a−2b+2b=c+2b
5a=2b+c
Step 3: Divide both sides by 5.
5a/5=2b+c/5
a=2/5b+1/5c
-1 will be your answer
rise over run
3-1 = 2
-4 + 1 = -3
2-1 = 1
-3 + 1 = -2
hope this helps
