Ответ:
The rate of change( the slope) is -40. This means that each week, she has 40 less songs to download. I know this because we start at 200 songs( Initial value). then in one week we jump to 160 songs left. 200 - 160 = 40. 40 is a negative because we are decreasing the amount.
An equation that would be appropriate for this scenario would be
y=-40x+200
I know this equation would work because 40 is the slope and 200 was already identified as the y intercept.
