Elaine is making a flower garden with rows of flowers. the garden is 20 yards long. she wants a total of 7 rows of flowers that are all the same width. which calculation should elaine use to decide how wide to make each row?

she would divide the length by the number or rows wanted

 so the calculation would be division

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
