The slope of the line is 2/3, so the angle is arctan(2/3) ≈ 33.69°.
Answer:
1. always
2. sometimes
Step-by-step explanation:
Two lines are coplanar if they lie in the same plane or in parallel planes. There is ALWAYS a plane which contains two parallel lines (see first attached image for details).
Two lines that lie in parallel planes are sometimes parallel. For example, see at second image. Planes and are parallel. Consider pair of lines and - they are parallel, but if you consider the pair of lines and , you can see they are not parallel.
Answer:
D
Step-by-step explanation:
This function passes the vertical line test.
The vertical line test test is done by drawing a vertical line anywhere on the graph. If the line goes through two points or more then it isn't a function.
