Answer:

B

Step-by-step explanation:

B is right because she is earning money, so the slope would have to be positive.

Next, the y-intercept of the 300 needs to be negative because she does not have the money to start with. It is also negative because you can think of it that you are subtracting the final babysitting money with 300.

Answer:

y = 25x - 300

Step-by-step explanation:

She has to save up 25 PER week and once she has enough, you subtract 300 since that's the cost of the bike
