Answer:
Positive Slope-A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises. Another words, the line goes up.
Negative Slope-A line with a negative slope is a line that is trending downward from left to right. In other words, the line's rise to run ratio is a negative value. Or the line goes down
Undefined Slope- An undefined slope is the slope of a vertical line! The x-coordinate never changes no matter what the y-coordinate is.
Zero Slope-A zero slope is just the slope of a horizontal line. The y-coordinate never changes no matter what the x-coordinate is.
