How can I plot graph only specific coordinate values from a PDE solved using the FEM method?

model = createpde(1);

R1 = [3,4,-2.5,2.5,2.5,-2.5,-0.5,-0.5,0.5,0.5]';

i made a pde mesh like this and solve problem by FED method.

but I want to plot a graph only the values of x=-2.5~2.5 when the y-coordinate is 0.

How can I extract it?

For a stationary computation:

What is the FED method ?
