(B) The equation of the chord of contact for a point $(x_1, y_1)$ with respect to the parabola $y^2 = 4ax$ is given by $yy_1 = 2a(x + x_1)$.Given the parabola $y^2 = 4x$,we have $4a = 4$,so $a = 1$.The point is $(x_1, y_1) = (-1, 2)$.Substituting these values into the formula:$y(2) = 2(1)(x + (-1))$$2y = 2(x - 1)$$y = x - 1$.Thus,the equation of the chord of contact is $y = x - 1$.

From the point $(-1, 2)$,tangent lines are drawn to the parabola $y^2 = 4x$. Find the equation of the chord of contact.
