ANSWER:
Explanation:
The slope is the inclination of the line with respect to the x-axis and indicates the vertical units that the line rises for each horizontal unit on the graph.
That is, if the slope is 1, the line increases by 1 both vertically and horizontally, but if the slope is 2, it increases by 2 vertically but 1 horizontally.
Therefore, we can determine the slope of each line.
