Question

Line a passes through points (9, 6) and (2, 10). Line b passes through points (2, 11) and (9, 7). Are line a and line b parallel or perpendicular?

Answer 1

Answer: Parallel

Explanation:

We can find their slopes to determine if the lines are parallel or perpendicular.

`m_a=(10-6)/(2-9)=-(4)/(7)\\\\m_b=(11-7)/(2-9)=-(4)/(7)`

Since the equations of the lines are not the same but the slopes of the lines are equal, they are parallel.
