Equation of the line: y=4/5x-18/5
Answer:
-7000,-6000,-5000,-4000,-3000,-2000,-1000,0, 1000,2000,3000,4000,5000,6000,7000
Factor by using the rational roots test, and find that -2 is a root.
Replace X with -2 and simplify each term.
Divide the polynomial by (x+2)
The final answer becomes x = -2 and x = -1/2 +/-√3/2i
The first choice is the correct one.
The average rate of change is 1
2-1=1
3-2=1
4-3=1
