The number of pending corporate fraud cases stood at 545 at

The number of pending corporate fraud cases stood at 545 at the beginning of 2008

(t = 0)

and was 726 at the beginning of 2012. The growth was approximately linear.†

(a) Derive an equation of the line passing through the points

A(0, 545)

and

B(4, 726).

(Let t be the independent variable and ybe the dependent variable.)

y=1814x+545

(c) Use the equation found in part (a) to estimate the number of pending corporate fraud cases at the beginning of 2019. (Round your answer to the nearest whole number.)
cases

Solution

Line joining (0,545) and (4,726) is

y-545/181 = x/4

Or y = 181x+2180

Left topmost equation is right.
