As time passes, the amount of money in the account increases.
The amount in the account increases by $45.
The amount of money in the account when he started depositing is $197.
What is the rate of change of the linear function?
A linear function is a function that has one independent variable and one dependent variable. A linear function increases at a constant rate over a period of time. When drawn on a graph, a linear function is usually a straight line.
The form of linear functions is:
y = a + mx
Where:
- a = constant / slope
- m = y-intercept
- y = dependent variable
Looking at the given table, it can be seen that as time passes, the amount of money increases.
Rate of increase = (change in the amount of money) / change in the months
(557 - 467) / (8 - 6)
= 90 / 2
= $45
Amount in the account at the beginning = account balance at 6 months - (rate of increase x 6)
467 - (6 x 45)
467 - 270 = $197
