I used regression, and need to analyze what does that mean on the graph and table.

(I am not talking about the definition of P-value in general)

At least, I need to analyze variables of A, B, C, and D in P-value, coefficient, R-square on the table and the graph.

For example, the R square is 95%, so it's enough.

or B in the P-value is less than 0.5, so it's useful
