<image>As shown in the figure, a linear function \( y = kx + b \) (where \( k \) and \( b \) are constants and \( k \neq 0 \)) intersects with a direct proportional function \( y = ax \) (where \( a \) is a constant and \( a \neq 0 \)) at point P. The solution set for the inequality \( kx + b > ax \) is (___)
