Question

1. the data table shows the price of a certain stock on the first day of several months in one year. the equation of the trend line shown is $y = 0.2x + 13$, where $x$ represents the month and $y$ represents the price of the stock. in which month was the price of the stock about $14.80?

stock price

month	price ($)
march	12.76
may	14.54
july	14.28
december	15.40

Explanation:

Step1: Substitute y with 14.80

$14.80 = 0.2x + 13$

Step2: Subtract 13 from both sides

$14.80 - 13 = 0.2x$
$1.80 = 0.2x$

Step3: Solve for x

$x = \frac{1.80}{0.2}$
$x = 9$

Step4: Map x=9 to month

Month 9 corresponds to September.

Answer:

September (month 9)
