The slope tells you the rate of change. Change in what? Well, that depends on what your data is!
If your vertical axis is speed(mph) and your horizontal acess is time(seconds), then a slope of 1/3 tells you that at the current rate of change, you would increase speed by 1 mph in 3 seconds,
Whatever your data is, this holds true - slope tells you how quickly one variable is changing relative to another.
It shows the rate of change of the Algebraic Function that in turn defines the shape that the data forms on the graph.
IT reveals patterns and trends. That a nonlinear graph might not be able to show.
The line that reflects the general pattern of a graph is called a trend line.
A best fit graph to some data is exactly that: it is a line which fits the data best according to some optimality criterion. There is a always a trade off in fitting a line to data: one can change the number of degrees of freedom of the underlying equation, which affects how close the line can get to the data points. With more degrees of freedom, the line can more closely approximate the data. This is not to say that more degrees of freedom are better: with too many degrees of freedom, one is merely fitting to the noise in the measurement of the data, and the line will predict subsequent data poorly, when both interpolating and extrapolating the existing data. This is an example of Occam's Razor: one must pick the simplest model which adequately fits the data.
A line graph.
A bar graph or line graph usually are the best ways. also tables, charts can work .
You would use a bar graph to show data changes over time or to show comparisons among items. A line graph can also be used to show data changes over time or comparisons. A pie/circle graph would be used to show the relative amount/size of items in a data set. A scatter plot is used to show trends and similarities in a large number of data points.

It tells you if the data raised alot or little.(Ex:if the first point is x95:y5 and the second is x95:y90 it is a steep slope.)
The line on the graph that shows what the data is saying.
You can draw a line graph if you have-- the slope of the line and one point on the lineOR-- two points on the line
No - a line graph may peak and trough depending on the data marked on the graph - a bit 'like join the dots'.
"Slope" is the steepness of the line on any graph.
it is impossible to tell the slope of a line graph without proper points to evaluate from.
The slope of each point on the line on the graph is the rate of change at that point. If the graph is a straight line, then its slope is constant. If the graph is a curved line, then its slope changes.
The graph of the equationy = 2x + any numberis a straight line with a slope of 2.
the slope.
acceleration
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
A straight line graph with negative slope slants downward from left to right.
