Q. Read the description of a proportional relationship.

\newline

Scarlett wants to save up some money to buy a new smartphone, so she babysits on the weekends. There is a proportional relationship between the time Scarlett spends babysitting (in hours),

x

, and the amount of money she earns babysitting (in dollars),

y

.

\newline

For

1

hour of babysitting, Scarlett earns

\$6

. Write the equation for the relationship between

x

and

y

.

\newline

y =

____

Identify rate of earning: Identify the constant rate of earning per hour. Scarlett earns $\$6$ for every hour she babysits.
Write proportional relationship equation: Write the equation representing the proportional relationship. Since the relationship is direct, the equation is $y = 6x$ , where $y$ is the total earnings and $x$ is the number of hours worked.
