Question

I have a test next week and I don't know or understand how to do this question. Can someone explain or show me how to find the answer?

Answer 1

$50 are added per week
$550 is the starting amount

since x = # of weeks, and 50 is being multiplied by that, it is known that each week, you are earning an additional $50
since when x = 0, aka at the beginning, y = 550, that is the amount you started with
