Question

Wanda has $640 in her checking account. she pays her landlord $75 per week for rent.

Answer 1

Answer:

Option B is correct

$y = -75x+640$

Step-by-step explanation:

The equation of line is given by:

$y=mx+b$

where, m is the rate or slope and b is the initial amount.

As per the statement:

Wanda has $640 in her checking account.

She pays her landlord $75 per week for rent.

Assume that the number of weeks be x.

Let us assume that the y represented the money in the account after x weeks.

then;

the function becomes,

$y = 640-7x$

or

$y = -75x+640$

Therefore, the function best models the linear relationship is, $y = -75x+640$

Answer 2

The answer is y = 640 - 75x
As her balance starts at a fixed point ( 640)
and decrease every x weeks by 75
