The second table does not represent a function
Change to y=Mx+b format. y=-2x+5. (0,5) is the y intercept, and -2/1 is the slope. Remember rise/run.
You need to annex the zeroes. Don't worry about the 9 zeroes. Just do 5*1 which equals to 5. Then add the 9 zeroes back.
5,000*1,000,000 = 5,000,000,000
