Find the Domain -7x-9y=1

Problem

−7*x−9*y=1

Solution

1. Identify the type of equation. This is a linear equation in two variables, x and y

2. Solve for y in terms of x to determine if there are any restrictions on the input values.

−9*y=7*x+1

3. Isolate y by dividing both sides by −9

y=−7/9*x−1/9

4. Analyze the resulting function. Since the expression is a polynomial (specifically a linear function), there are no denominators containing x and no even roots.

5. Conclude that the function is defined for all real numbers.

Final Answer

Domain: *(−∞,∞)
