Answer: Non-Linear.
Explanation:
The first equation is in the form of a linear equation, but the second equation is in the form of a non-linear equation where the variable y has an exponent of 1/2. When we plot the graph of these two equations, they do not intersect at a single point, which is a characteristic feature of non-linear equations.
To solve this system of equations, we can use numerical methods such as substitution or elimination. However, it is important to note that non-linear equations can have multiple solutions or no solutions at all.
