Answer
$y=x-3$
Work Step by Step
Create a table with some values that satisfy the statement.
$\underline{Bea's Age, x}\ \ \ \ \underline {Ty's Age, y}$
$\ \ \ \ \ \ \ \ \ 5\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2$
$\ \ \ \ \ \ \ \ \ 6\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3$
$\ \ \ \ \ \ \ \ \ 7\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4$
If Ty is 3 years younger than Bea, then Ty's age is 3 years less than Bea's age.
$y=x-3$
Graph the points in the table and connect with a line.
