∙ 13y agoThis 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).

∙ 13y agoacceleration 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.
Acceleration is represented on a graph by the slope of the velocity-time graph. A positive slope indicates acceleration in the positive direction, while a negative slope indicates acceleration in the negative direction. A horizontal line on the graph represents constant velocity, with zero acceleration.
The slope of a velocity vs. time graph represents acceleration. A positive slope indicates acceleration in the positive direction, a negative slope indicates acceleration in the negative direction, and a horizontal line indicates constant velocity.
The slope of a speed-time graph represents the acceleration of the object. A positive slope indicates acceleration in the positive direction, a negative slope indicates acceleration in the negative direction, and a zero slope indicates constant speed.
The answer depends on whether the graph is that of speed v time or distance v time.
The slope of the instantaneous speed-vs-time graph represents the acceleration of the object. A positive slope indicates the object is accelerating in the positive direction, while a negative slope indicates acceleration in the negative direction. The steeper the slope, the greater the magnitude of the acceleration.
The slope of the tangent to the curve on a velocity-time graph represents the acceleration of an object. Positive slope indicates acceleration in the positive direction, negative slope indicates acceleration in the negative direction, and zero slope indicates constant velocity.
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
A changing slope on a velocity-time graph indicates that the object's acceleration is changing. If the slope is increasing, the acceleration is positive, and if the slope is decreasing, the acceleration is negative. A flat slope indicates constant velocity.
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
On a speed vs. time graph, acceleration is represented by a non-zero slope. If the slope of the graph is increasing, it indicates positive acceleration (speeding up). If the slope is decreasing, it indicates negative acceleration (slowing down).
On a position vs. time plot with constant acceleration, the graph would be a curved line, not a straight line. The curve would be concave upward if the acceleration is positive and concave downward if the acceleration is negative. The slope of the line would represent the velocity at any given time.
When a negative acceleration is graphed, the line slopes downward on a velocity-time graph. This is because negative acceleration causes a decrease in velocity over time, resulting in a negative slope on the graph.
