4 Lines of symmetry
x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.
There is no such thing as 8 lines of symmetry. A circle, for example, has infinitely many lines of symmetry.
If you mean the letter x, it has four lines of symmetry.
the letter X has two lines of symmetry

A regular polygon with x sides has x lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. For example, a regular hexagon has 6 lines of symmetry, one for each pair of opposite sides. The formula for calculating the number of lines of symmetry in a regular polygon is equal to the number of sides x.
