Not always because it can also be negative

False.
You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.
For a negative slope, the rise is negative and the run is positive.
Positive correlation has a positive slope and negative correlation has a negative slope.
No because the slope of a line can be positive or negative
The answer depends on the signs of the original intercepts.x negative, y negative: negative slope becomes less negative and could go positive.x negative, y positive: positive slope becomes greater.x positive, y negative: positive slope becomes less positive and could go negative.x positive, y positive: negative slope becomes more negative.For 1 and 3, the slope changes sign when the y intercept crosses the origin.
A positive slope is simply a slope going upward on a graph from left to right. A negative slope is a slope going downward from left to right. Often, negative slopes are the reverse of positive slopes and are both depending on the person's direction.

If the pressure is increasing then the slope is positive. If the pressure is decreasing then the slope is negative.
Acceleration is a vector quantity and can have positive, negative, or zero slope. A positive slope indicates an increase in speed, a negative slope indicates a decrease in speed, and a zero slope indicates constant velocity.
Never.
larger slope if positive and a smaller slope if negative
