Question

Use the slopes to describe each line as slanting downward, slanting upward, horizontal, or vertical. explain your answer.

(1,3) and (1, -10)

Answer 1

Explanation:

The slope of 3 and -10.

If the slope is above 0, the line is increasing.

If the slope is at 0, it's a horizontal line or straight. Vertical If the run is 0.

If the slope is below 0, the line is decreasing.

3 is slanting upward, the slope is greater than 0 therefore the line is increasing.

-10 is slanting downward, the slope is less than 0 therefore the line is decreasing.
