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
