The graph of the identity function is a diagonal line that passes through points where the x-coordinate is equal to the y-coordinate, such as \((-2, -2)\), \((-1, -1)\), \((0, 0)\), \((1, 1)\), and \((2, 2)\). Therefore, the correct response is the first option:
A diagonal line is graphed on the coordinate plane. It passes through points \((-2, -2)\), \((-1, -1)\), \((0, 0)\), \((1, 1)\), and \((2, 2)\).
