Answer:
The center is [-1,-2
Step-by-step explanation:
subtract the fee from the total to get the amount actually spent on songs
23.80-7 = 16.80
divide that amount by price per song to get number of songs downloaded
16.80 /0.20 = 84 songs
The cost equation has a constant rate of change, so this is a line of the form:
y=mx+b, you are told that there is a flat fee of $5 and an hourly rate of $2 so
y=2x+5
The y-intercept (the value of y when x=0) is 5. The point (0,5) on the line.
