Value of x in 1974 is 0
Value of x in 1984 is 10
Value of x in 1994 is 20
Value of x in 2004 is 30
Price of tickets in 1974 is $1.89 Price of tickets in 1984is$3.20
Price of tickets in 1994 is $4.51 Price of tickets in 2004 is$5.82

### What are the price of tickets?

A linear function is a function that has a single variable raised to the power of 1.
An example of a linear function is 0.131x+1.89
Where:
• 1.89 is the constant. It is the price of ticket in 1974.
• 0.131 is the rate of increase in the price of tickets with time
Value of x in 1974: 1974 – 1974 = 0
Value of x in 1984: 1984 – 1974 = 10
Value of x in 1994: 1994 – 1974 = 20
Value of x in 2004: 2004 – 1974 = 30
Price of tickets in 1974 : 0.131 (0) +1.89 = 1.89
Price of tickets in 1984 : 0.131 (10) +1.89 = 3.20
Price of tickets in 1994 : 0.131 (20) +1.89 = 4.51
Price of tickets in 2004 : 0.131 (30) +1.89 = 5.82
