A man decides to take out $70 per month from his savings account. After 63 months, he has $2720 in his account. Identify the slope and point, then write a linear equation in point-slope form which models the amount in the savings account in terms of the number of months.

Answer:

the Point are: ( 63, 2720 )

Slope is : - 70

linear equation in point-slope : y = 7130 - 70x

Step-by-step explanation:

given the data in the question;

let x represent number of months he is taking money from his account

so

y = 70x +  2720

so total amount in his account will be;

⇒ 70×63 + 2720

= $7,130

for each month, ( say x in number) he takes out $70,

let y be amount in account at (x) month, so;

y = 7130 - 70x

the Point are: ( 63, 2720 )

Slope is : - 70

linear equation in point-slope : y = 7130 - 70x
