brooke opens a credit card with an APR of 28.99%. how much is charged in interest this month if her balance is $500?
Varvara68 [4.7K]
To find the interest accrued for the month, you will use the interest formula I = prt.  P stands for the principal (the amount of money borrowed), r is the interest rate, and t is the time period.  Because the interest rate is an annual (yearly) interest rate, you will use the fraction 1/12 in your calculation.  The math would be $500 x 0.2899 x 1/12.  This equals an interest charge of $12.08.

Answer:

-2/3

Step-by-step explanation:

We need to pick two points on the line.

(-2,0) and (1,-2)

We can use the slope formula

m = (y2-y1)/(x2-x1)

m = ( -2-0)/(1 - -2)

   = (-2-0)/(1+2)

    = -2/3
