  • The image displays a standard two-dimensional Cartesian coordinate system with the horizontal axis labeled with 'x' and the vertical axis labeled with 'y'.
  • A straight line is drawn through the first quadrant, representing the linear equation \(y = a + bx\).
  • Several points are marked on the graph, corresponding to coordinates on the line.
  • These marked points include \(P_1\) at the coordinates \((x_1, y_1)\), \(P_2\) at the coordinates \((x_2, y_2)\), and a final point \(P_n\) at \((x_n, y_n)\).
  • Vertical lines are drawn from each point \(P_1\), \(P_2\), and \(P_n\) down to the horizontal x-axis, illustrating the projection of these points onto the axis.
