Step-by-step 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.
