Answer:
the symmetric property of equality
Step-by-step explanation:
If 5 = x + 2, then x + 2 = 5. both have an equation so it represents an equation.
Reflexive property of equality states that a=a
Symmetric property of equality states that
If c=a+b then a+b= c
In the given statement
If then
The given statement represents the symmetric property of equality

The equation for a parabola with directrix y = –p and focus (0, p)
The distance between vertex and directrix is P
Also the distance between vertex and focus is also P
Focus (0,p) so focus lies on y axis
Directrix line is paralled to focus point
So Directex crosses the x axis .
Hence line of symmetry lies is the y-axis.
The graph is attached below.
