Question

y = 2x + 8
(16,40)
(3,14)
money spent (dollars)
number of games played in the arcade
use the equation of
the trend line to
predict the amount
of money spent if
18 games are played
in the arcade.
$?

Explanation:

Step1: Identify the variable

The number of games played is \( x \), and we need to find the money spent (\( y \)) when \( x = 18 \). The equation is \( y = 2x + 8 \).

Step2: Substitute \( x = 18 \) into the equation

Substitute \( x = 18 \) into \( y = 2x + 8 \):
\( y = 2(18) + 8 \)

Step3: Calculate the value

First, calculate \( 2(18) = 36 \). Then, add 8:
\( y = 36 + 8 = 44 \)

Answer:

44
