    The question is faulty written. I'll solve it assuming values for one variable and provide the answer to guide the student in their own question

    Answer:

    x=t

    y=-1-9t

    Step-by-step explanation:

    Parametric Equations

    Given an explicit relation between variables x and y, we can find expression for both of them in term of a third parameter t, such as

    x=f (t)

    y=g (t)

    provided the main relation holds.

    we have the equation

    9x+y=-1

    There are infinitely many forms to find parametric expressions for the variables, let's assume

    x=t

    Solving the equation for y

    y=-1-9x=-1-9t

    Thus the parametric equations are

    x=t

    y=-1-9t
