Answer:
Balance(m) = 900-40m
After 9 months, Felicia has $540.
Step-by-step explanation:
Balance = 900 - 40m
So after 9 months, 900-40*9=900-360=540.
None are given. You have to invent your own points that satisfy the given equation.
Examples: If x = 0, y = -5000 => (0,-5000)
If x = 2, y = -(2)^2 + 160(2) - 5000 = 4 + 320 - 5000 => (2, -4676)
and so on. Find as many such points as you want, using the same approach.
Suppose that the height (in centimeters) of a candle is a linear function of
the amount of time (in hours) it has been burning.
Let x be the amount of time in hours
Let y be the heoght of a candle in centimeters
The two points are then as (9,24.5) and (23,17.5).














Now plug in x=21, we get

Thus the height of the candle after 21 hours is 18.5 centimeters.
