2000 is the y-intercept, it is the amount of money in the account initially.

<h3>Exponential function</h3>

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the multiplier, y, x are variables.

Let y represent the amount in the bank after x years.

Given the function y=2000(0.64)ˣ

Hence:

a = 2000, b = 0.64

0.64 = 1 + x

x = -0.36 (36% decrease)

2000 is the y-intercept, it is the amount of money in the account initially.

Line passing through (2,5) and the m= -5/6
kiruha [24]

Answer:

y - 5 = (-5/6)(x - 2)

y - 5 = (-5/6)x + 10/6

y - 30/6 = (-5/6)x + 10/6

y = (-5/6)x + 20/3
