Answer:
The answer to your question is y = -2x + 9
Step-by-step explanation:
A (9, 9)
B (-2, 13)
Process
1.- Find the slope
m =
m = - 2
2.- Find the line equation
(y - y1) = m (x - x1)
y + 9 = -2 (x - 9) y + ? = [ ] ( x + [ ])
y + 9 = - 2x + 18
y = - 2x + 18 - 9
y = -2x + 9
Answer:
She'll have $661 in the account in 2022.
Step-by-step explanation:
