Graph with Axis Displaying a Line

A simple Cartesian coordinate system is shown, featuring a clear grid and labeled axes. A straight blue line is plotted, extending diagonally across the graph. The line passes through the origin, indicating a direct relationship between the x and y values, and appears to represent the equation y=x. The graph includes numerical labels along both the horizontal and vertical axes, ranging from negative to positive values.
