Question

You were born 2 years before your sister. Write the equation of the additive relationship where x
is your age and y
is your sister’s age.(1 point)
Responses

y=x+2
y equals x plus 2

x=y+2
x equals y plus 2

y=x−2
y equals x minus 2

x=y−2

Answer 1

The correct equation for the additive relationship where \( x \) is your age and \( y \) is your sister’s age (given that you were born 2 years before your sister) is:

\[ y = x - 2 \]

This means your sister is 2 years younger than you.
