What does a positive slope indicate about a line?
Back
A positive slope indicates that as the x-values increase, the y-values also increase, resulting in an upward slant from left to right.

What does a negative slope indicate about a line?
Back
A negative slope indicates that as the x-values increase, the y-values decrease, resulting in a downward slant from left to right.

What does a zero slope indicate about a line?
Back
A zero slope indicates that the line is horizontal, meaning there is no change in y as x changes.
