Question

In a plane, if one line has an undefined slope and another line has a slope of zero, what can you conclude

Answer 1

Answer:

The lines are perpendicular

Step-by-step explanation:

Because an undefined slope is just a vertical line, and a line with a slope of zero is just a vertical line. A vertical line and a horizontal line are perpendicular.

Answer 2

Answer:

You can conclude that the lines are perpendicular, and will cross at exactly one point.

Step-by-step explanation: If one line has a zero slope, and the other's slope is undefined, that means one line is exactly vertical, and the other is exactly horizontal. This means that they will cross at exactly one point, and are perpendicular.
