Question

Due to a crackdown on fraudulent corporate​ reports, the number of restatements of facts in such reports has increased approximately linearly from 404 restatements in 2002 to 1793 restatements in 2004. Let (N) be the number of restatements in the year that is t years in 2000. Find an equation of a linear model to describe.

MULTIPLE CHOICE
(A.) n=985t + 694.5
(B.) n = -694.5t + 985
(C.) t= 694.5n +985
(D.) n= 694.5t - 985


PLEASE EXPLAIN AND SHOW WORK

Answer 1

(D.) n = 694.5t - 985

Explanation:

2002 - 2004 = 2

1793 - 404 = 1389

1389/2 = 694.5

There are about 694.5 cases per year from 2002 to 2004.

404 - 2(694.5) = -985

The y intercept of the graph would be -985(if the graph could go negative).

n = 694.5t - 985
