Two linear equations are represented by using the tables below. the data points for equation a are graphed on the coordinate plane below and are connected by using a straight line.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)
