3x^2y^2D+2xy^3-12y^2-24xyd how do you find the implicit Differentiation of this equation

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

Me asap! what is the slope of this line? enter your answer in the box.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
