1. Describe the relationship between the following lines: Y = 4x – 6
X + 4y = 8
A. They are parallel.
B. They are perpendicular.
C. They intersect but are not perpendicular.
2. Find the equation of the line parallel to 2x - 3y = 9, passing through the point (-6, 3).
A. Y = 2/3x + 7
B. Y = -2/3x – 1
C. Y = -3/2x – 6
D. Y = 3/2x + 9

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.
