5. If `y + 3=m_1(x +2)` and `y + 3 = m_2(x + 2)` are two tangents to the parabola `y^2 = 8x` , then

If y+3=m_1(x+2) and y+3=m_2(x+2) are two tangents to the parabola y_2=8x , then (a)m_1+m_2=0 (b) m_1+m_2=-1 (c)m_1+m_2=1 (d) none of these

If y+b=m_(1)(x+a) and y+b=m_(2)(x+a) are two tangents to the paraabola y^(2)=4ax then

If y+a=m_(1)(x+3a),y+a=m_(2)(x+3a) are two tangents to the parabola y^(2)=4ax , then

If the line (y-b)=m_(1)(x+a) and (y-b)=m_(2)(x+a) are the tangents to the parabola y^(2)=4ax then

If a_(1)x+by+c=0 and a_(2)x+by+c=0 are two tangents to the parabola y^(2)=8x(x-2a), then

If y+b=m_1(x+a)& y+b=m_2(x+a) are two tangents to the parabola y^2=4ax then |m_1m_2| is equal to:

The common tangent to the parabolas y^(2)=8x and x^(2)=-4y is

y=2x+3 is a Tangent to the parabola y^(2)=4a(x-(1)/(3)) then 3(a-5)=
