$86,800,000 in scientific notation

8.68·10^7

Step-by-step explanation:

Scientific notation is a number with no zeros between 1-10 that is multiplied by a number of 10's so here we just take away 868 and add a decimal point to make it between 1-10 8.63

then we count our zeros and add the amount of numbers behind the decimal point

thats how many 10's there will be(7)

our answer is 8.63·10^7

if i remember a function on a graph is always a straight line so i think graph 1 would be your answer :)

hope i helped :D
