What does the slope of a trend line tell you about the relationship between two quantities?
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 true when drawing a trend line for a series of data on a scatter plot?
Based on the information given in the question, nothing particularly is true. The line need not be straight, or even a smooth curve. There need not be any points on the line but there need not be any points not on it.
Does a trend line always pass through every point on a scatter plot?
No, that would be quite unusual if if did, although not impossible.
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).
Does the trend line always pass through every point on a scatter plot?
No. When you draw a best line of fit on the scattered plot, the line would not be straight.
What is a slope'?
A smooth line drawn between points on a graph to reflect the general trend.
Which is the equation of a trend line that passes through the points (3 95) and (11 12) Round values to the nearest ten-thousandths.?

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.
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.
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.
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.
How do you find the trend 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.http://wiki.answers.com/What_does_a_trend_mean_on_a_line_graph#ixzz18qYakrsc
What is a trend of a line on a cartesian coordinate plane?
The slope of a straight line is often described by the rise over the run. This is the ratio of the vertical distance between two points and the horizontal distance between them (taken in the same order).
What is the trend of a graph?
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.
Can trend projections have a negative slope?
Yes. Try, for example, population projections for an endangered species.
What does the slope of a trend line tell you about the relationship between two quantities?
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.
