If the slope of the trend line between variables X and Y is m, then an increase in value of 1 unit in X is associated with an increase of m units in the value of Y. The relationship is one of association, not of cause-and-effect.

What is the most accurate trend line on a scatter plot showing the relationship between two sets of data?
Line of best fit
What is the slope of a trend line that passes through the points (1 3) and (10 25)?
Jeremy surveyed students in his class about their spending habits in the school cafeteria. He used the data to create a scatterplot. How Students Spend Money in the Cafeteria Which is the equation of his trend line?
What is the difference between a trend line and a line of best fit?
A trend line is graphed from a linear, exponential, logarithmic or other equation, and trys to fit the sorted data that you have. But it may or may not be correlated. The line of best fit is the trend line that best fits your data, having a high correlation. R closer to 1.
What is the definition of linear equation?
A linear equation has a constant rate of change, or slope (change in y (dependent) value over change in x (independent) value), when graphed forms a straight trend line, and is in the format y=mx+b (y is dependent value, m is slope, x is independent value, and b is the y-intercept (the value of y when x=0).
Are regression and trend line the same?
yes.
What does trend mean you math terms?
A trend is a math term. It is on a line graph. It is a slope between two variables.
What is a slope'?
A smooth line drawn between points on a graph to reflect the general trend.
When is there no trend line for a scatter plot?
When no possible relationship between the two variables in question is statistically significant.
What trend line means?
The trend line for a scatter plot is a line that best captures the nature of the relationship between two variables. It may or may not be straight.

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 is the slope of a trend line?
It is the rise/run for the line.
Why would a linear trend equation based forecast be dangerous?
The relationship between the variables may not be linear.

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.
