The graph has the following key features:
(1) it shows the checking balance as a function of time (ie., at a given week)
(2) the graph is linear, showing a linear relationship between the balance and time. This is because the amount deposited is the same every week.
(3) the slope of the line is 134.12, since Terrance deposits $134.12 every week. The graph's y axis has different scale which makes the graph appear to have a slope close to 1, but, nevertheless, the linear function has slope of 134.12.
(4) the y-intercept is at 207.43 because at time 0 (week 0) there was a starting balance of $207.43
(5) The function in slope intercept form:
y = 134.12*x + 207.43
