A man takes out $70 a month from his savings account. After 63 months he has $2720 in his account. Identify the point and slope then write any linear equation in point slope form.

Answer 1

P = A - 70M, P=amount in the account after M months, starting with A amount in the account

2720 = A -70(63)

A = 2720+4410 = 7130

P=70M + 7130 or

y=70x +7130 where 70 = slope and y intercept = 7130 = original amount in the account

70=slope (0,7130) = a point = the y intercept
