Write both the equations in the same form:
ax + by + c = 0
or
y = mx + c
or
x = ny + k
If each coefficient and constant of one equation are a multiple of the coefficient and constant of the other, then the two lines are the same. If not, they are not.

Presumably the question concerned a PAIR of linear equations! The answer is two straight lines intersecting at the point whose coordinates are the unique solution.
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
