Question

which of the following are the correct properties of slope? check all that apply. a. the slope of a flat line should be exactly 0. b. a negative slope means that the line moves down from left right. c. the slope of a flat line is smaller than the slope of a steep line with a positive slope. d. the slope of a flat line is undefined. e. a negative slope means that the line moves up from left to right.

Explanation:

• A flat line has no vertical change, so its slope is 0.
• A negative - slope indicates a line that descends from left to right.
• A positive - slope line rises from left to right and a flat line's slope of 0 is less than a positive slope.
• The slope of a vertical line is undefined, not a flat line's.

Answer:

A. The slope of a flat line should be exactly 0.
B. A negative slope means that the line moves down from left to right.
C. The slope of a flat line is smaller than the slope of a steep line with a positive slope.
