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 ratio of rise to run?
It is the slope.
What is the difference between a line with a slope of zero and no slope?
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
If the slope of the green line is -3 what is the slope of the red line?
The lines below are perpendicular. If the slope of the green line is -1, what is the slope of the red line?
What relationship exist between two variables when their ratio is constant?
Direct proportionality. Their graph would be a straight line through the origin, with the slope equal to the ratio.
What is the slope of a line ratio for any two points on the line?
Slope ratio is: (y1-y2)/(x1-x2)
The ratio of rise to the run of a line?
Is the modulus, gradient or slope of the line.
The ratio of a line's vertical change to its horizontal change?
the slope
What Is a ratio that compares the vertical change to the corresponding horizontal change as you move from one point to another on a line?
Slope of the line
What are the properties of a slope?
The slope is the ratio of the vertical increase divided by the horizontal increase. The slope of a flat line is 0. The slope of a flatter line is smaller than the slope of a steeper line. A positive slop indicates that the line move up from left to right. A negative slope means that the line moves down from left to right.
The Ratio of a vertical change to the corresponding horizontal change in a line?
slope
What is the ratio of a vertical change to the corresponding horizontal change in a line?
Slope.
What is the ratio of a vertical change of the corresponding horizontal change in a line?
Slope.
What is the ratio of a vertical change to the corresponding horizontal change of a line?
Slope.
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 ratio of the vertical change (rise) to the horizontal chnage (run) of a nonvertical line?
It is called the slope of a line.
What is the slope and y-intercepect of a line?
The slope of a line is its "rise over run", or the ratio of its change in y to its change in x. The y intercept is a point where a line intersects the y axis.
