Answer:

$y=-6x-17$ (B)

Step-by-step explanation:

$y=mx+b\\m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{1--5}{-3--2} = \frac{6}{-1} = -6\\y=-6x+b\\$

Plug in one of the two points for X and Y

(-3,1)

$1=-6(-3)+b\\1=18+b\\b=-17\\\\y=-6x-17$

If you borrow $900 for 6 years at

attashe74 [19]

Answer:

$1278

Step-by-step explanation:

First you would need to find out how much the annual interest rate is so you would find out what 7% of $900 is which is 63 meaning that there is an annual fee of $63 and since it was for 6 years you would multiply $63 times 6 to get 378 and then to find the total amount you would pay you have to add the interest to what you borrowed so you would do $900 + $378
