5. Bank account A starts with $5,000 and grows by $1,000 each week, Bank account B starts with $1 and doubles each week.
a. Which account has more money after one week? After two weeks?
b. Here is a graph showing the two account balances. Which graph corresponds to
which situation? Explain how you know.
40,000
30,000
amount in dollars
20,000
10,000
15
10
number of weeks
c. Give a choice, which of the two accounts would you choose? Explain your reasoning.

hi there!

the answer will be d: 2

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
