we need to solve this graphically first and then test for x-axis symmentry

to test for x-axis symmentry, replace y with (-y) and simplify the equation.

if the equation is equivalent to the original equation, then the graph is symmentrical to x-axis


-(2)/(x)=y+2_{}

now let's test for (-y) and compare


-(2)/(x)=-y+2

since the resulting equation is not similar to the original equation, the equation is not symmentrical to the x-axis.

now let's test y axis

replace x with (-x)


\begin{gathered} -(2)/(x)=y+2 \\ -(2)/((-x))=y+2 \\ (2)/(x)=y+2 \end{gathered}

the equation is not symmentrical to the y-axis

from the calculation above, the equation is not symmentrical to both x and y axis.
