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

The slope of a line illustrates the direction of the line

The two lines are perpendicular lines

From the question, we understand that:

As a general rule,

A vertical line and a horizontal line will meet at a right-angle

Hence, the conclusion about the two lines is that, the two lines are perpendicular lines

See attachment for illustration

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.
