A line has an undefined slope and goes through the point (–5, –8). Which of the following must be true about the line? Select all that apply. A. The point (–5, –4) is on the line.

B. The point (2, –8) is on the line.

C. The line goes through the origin.

D.
The line never crosses the y-axis.

E. The line never crosses the x-axis.

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.
