Answer:
the answer is C because :
1) There is no change in the overall cost, so the slope stays the same. since the a dependent variable is cost,
2) It stays on the y axis, and the amount of photocopies is on the x axis.
3)The total amount of money for 8 copies is $1.60,
4) so you would just plug those into the graph and bam!, find that the answer C is 100% correct.
