Is there a relationship between the sign of the slope of a line and the angle the line makes with the x-axis?
Yes, there a relationship between the sign (positive or negative) of the slope of a line and the angle the line makes with the x-axisWhen a line slopes up from left to right, it has a positive slope. This means that a positive change in y is associated with a positive change in x. The steeper the slope the greater the rate of change in y in relation to the change in x.When a line slopes down from left to right, it has a negative slope. This means that a negative change in y is associated with a positive change in x.
The slope of a line is the ratio of the?
vertical change to the horizontal change between any two points on the line. study island.
What can you say about the relationship between a correlation r and the slope b of the least squares line form of data?
You can say that the correlation is positive if and only if the slope is positive. The correlation is zero if and only if the slope is zero. And the correlation is negative if and only if the slope is negative. On the other hand, slope does change when your measurement units change, while correlation does not change. (For example, the correlation between height in inches and weight in pounds will be the same as the correlation between height in centimeters and weight in kilograms, as long as both sets of measurements were taken on the same observations.)
What is the vertical change when the slope of a line is expressed as the ratio of the rise to the run?
The vertical change between two points separated by a horizontal difference of Dx is Dx*slope = Dx*Rise/Run
How do you get the slope for 4 5 6 8?
To find the slope between two points: slope = change_in_y/change_in_x Thus for the points (4, 5) and (6, 8), the slope between them is given by: slope = (8-5)/(6-4) = 3/2 = 1½ = 1.5
What is an average slope on a topographic map?
The average slope is the ratio of the change between two points
How do you find slope on a distance vs. time graph?
The slope is the change in distance between any two points divided by the change in time between them.
The constant rate of change between two points on a line?
The constant rate of change between two points on a line is called slope.
Fact must be known to determine the average slope between the two points?
The distance between two points must be known to determine the average slope between the two points. You must also know the change in elevation.
What is nonvertical line is the ratio of the vertical change to the horizontal change between any two points on a line?
The slope.
Is there a relationship between the sign of the slope of a line and the angle the line makes with the x-axis?
Yes, there a relationship between the sign (positive or negative) of the slope of a line and the angle the line makes with the x-axisWhen a line slopes up from left to right, it has a positive slope. This means that a positive change in y is associated with a positive change in x. The steeper the slope the greater the rate of change in y in relation to the change in x.When a line slopes down from left to right, it has a negative slope. This means that a negative change in y is associated with a positive change in x.
In addition to the distance between the two points what other fact must be known to determine the average slope between the two points?
change in elevlation
Is the rate of change between any two points on a line?
That's called the line's slope.
The slope of a line is the ratio of the?
vertical change to the horizontal change between any two points on the line. study island.
How do you get the slope of a line on a graph?
Take a tangent at the point where you want the slope. Then the slope of the graph at that point is the slope of the tangent, which is found by taking another point on the tangent and then taking the change in y between the two points and divid it by the change in x.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
How does the slope differ from average rate of change?
They are the same for a straight line but for any curve, the slope will change from point to point whereas the average rate of change (between two points) will remain the same.
