(See explanation below for further details).
Step-by-step explanation:
Let be a parametric curve represented by 
and 
, where 
is the parametric variable.
The curve is represented graphically with the help of a graphing tool, whose outcome is included in the image attached below. The corresponding rectangular equation is found by eliminating t of each equation.
and 
The parametric equations represents a linear function (first-order polynomial).
