Every month, ms. thomas pays her car loan through automatic payments (withdrawals) from her savings account. she pays the same amount on her car loan each month. at the end of the year, her savings account balance changed by -$2175 from payments made on her car loan. what is the change in ms. thomas’ savings account balance each month due to her car payment?

answer:

$1465.5

step-by-step explanation:

ms. thomas pays the 'same' amount as her car loan each month through car payments.

total amount payed at the end of the year for car loan = -$2931

change in ms. thomas' savings account each month (with respect to car loan) =-2931/12 = -$244.25

so, to to calculate the total change to ms. thomas's savings account balance after paying for car loan for six months, we will simply multiply one month's amount with 6:

-$244.25 x 6 =   -$1465.5

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
