When finding the slope of the trend line what does the slope mean about the data of the scatterplot?

The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.

What graphs are used in finding trends in data?
Scatter graphs are best. Line graphs are OK if the trend is linear but not much good if the trend is non-linear.
What is the name of the method for drawing a trend line for the data in a scatterplot?
There are many methods, though the most popular is the method of least squares. This method minimises the sum of the squares of the vertical distances between each point and the corresponding point on the line.
What shows a correlation which may be positive or negative between two sets of data?
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.
What is a slope on a graph?
The line on the graph that shows what the data is saying.
How does finding the IQR hep you identify the variability of set of data?
The IQR gives the range of the middle half of the data and, in that respect, it is a measure of the variability of the data.

What is a trend on a graph?
It is the description of a slope of a line which connects from many points you mark to show a way that your graph data may increase or decrease. If it is decreasing, you have a downwards trend. If it is increasing, you have an upwards trend.
What is a graph that has a set of data plotted on a x-y plane as a dot for data points?
Scatterplot

What does a trend mean on a line graph?
It is a description of the Slope of the line with respect to the two variables you are plotting. In Statistics, you may be plotting AGE versus Car Mileage and a line drawn through the data is the Trend Line.
