This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
acceleration is the slope of the v t graph... so the acceleration is constant and negative. In other words, the object is slowing down at a constant rate.
a correlation on a graph is when the line of best fit is positive, negative or none.
to graph not only positive numbers, but negative ones as well
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
The trend of a graph is the slope of any line on the graph that indicated a positive or growth factor and/or a negative or decaying factor. If the slope goes negative, the graph's line will go down thus indicating decay. If the slope becomes positive, the graph's line will go up thus indicating growth.
The answer depends on whether the graph is that of speed v time or distance v time.
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
Acceleration is negative.
acceleration is the slope of the v t graph... so the acceleration is constant and negative. In other words, the object is slowing down at a constant rate.

True
Acceleration
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
No. A negative slope means that the object is slowing down. If the object were not moving, then its velocity would be zero. The graph would be a straight horizontal line that just lays there on the time axis.
a correlation on a graph is when the line of best fit is positive, negative or none.
