Q. Read the description of a proportional relationship. Every spring, Kenny plants colorful flowers in his garden. This year, he decides to plant petunias. He buys them at the garden store, brings them back home, and starts planting. There is a proportional relationship between the amount of time (in minutes) Kenny has been working in his garden,

x

, and the number of petunias he has planted,

y

. After working in his garden for

2

minutes, Kenny has planted

4

petunias. Write the equation for the relationship between

x

and

y

.

y = \_\_\_

Determine constant of proportionality: Determine the constant of proportionality, $k$ , using the information given: Kenny plants $4$ petunias in $2$ minutes.
Write equation for proportional relationship: Write the equation for the proportional relationship using the constant of proportionality, $k$ .
