Question

Determine the slope!

Answer 1

line 1 : zero

line 2 : positives

line 3 : undefined

line 4 : negatives

Explanation:

• A zero slope on a graph is a horizontal line that is parallel to the x-axis
• A line on a graph has an undefined slope when it is a vertical line
• A positive slope on a graph means that a line on the graph rises from left to right
• A line with a negative slope on a graph goes down and right (or up and left)
