If you have P1(x1, y1) and P2(x2, y2), the distance between them is:
[ (x2 - x1)2 - (y2 - y1)2 ]1/2

How do you find the slope of a line from its graph what is the formula for m?
The slope of a line is the rise divided by the run. In other terms, if, X = the horizontal distance between two points on a line and Y = the vertical distance between the same points, then m = Y/X
In addition to the distance between two points what other fact must be known to determine the average slope between the two points?
It is not necessary to know the distance between two points to determine the average slope. You just need to know the x and y coordinates of each point. The slope is defined as 'rise' divided by 'run' or the difference of the y's / difference of the x's. So if, Point 1 is (x1,y1) and point 2 is (x2,y2) then the slope would be: (y2 - y1) / (x2 - x1)
What does a distance time graph show?
A distance-time graph shows the movement of an object with respect to time. The average slope between any two points on the graph is equal to the average velocity of the object between those two points. The instantaneous slope (or derivative) at a point on the graph is equal to the instantaneous velocity of the object at that point.
Distance between two points?
the distance between two points is length
What is the slope of -5 3 and 3 3?
Two points don't have a slope. But the line between them does. The line between the points (-5, 3) and (3, 3) has a slope of zero.
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.
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.
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
How does the slope from the distance vs time graph compare to the average speed?
The slope of the line between two points on the distance/time graph is the same as the average speed during the time interval between those points.
Is Rise the vertical change between any two points on a line?
Yes. Slope is the distance between two different points, expressed as rise over run. The rise is the vertical distance and the run is the horizontal distance.
The run is the change between two points along a line?
The run, combined with the rise (the distance in units up) creates the slope of a line. In the slope 5/3 , 5 is the rise and 3 is the run, meaning that to find the next point on the line you would first move up five units, then go to the right 3 units.
How do you find the slope of a line from its graph what is the formula for m?
The slope of a line is the rise divided by the run. In other terms, if, X = the horizontal distance between two points on a line and Y = the vertical distance between the same points, then m = Y/X
How do you find a slope on a map?
If you mean a topographic map, then you just divide the distance between two contour lines by the change in height between the two points
In addition to the distance between two points what other fact must be known to determine the average slope between the two points?
It is not necessary to know the distance between two points to determine the average slope. You just need to know the x and y coordinates of each point. The slope is defined as 'rise' divided by 'run' or the difference of the y's / difference of the x's. So if, Point 1 is (x1,y1) and point 2 is (x2,y2) then the slope would be: (y2 - y1) / (x2 - x1)
How do you calculate the slope between two points?
The slope is calculated as: y1-y2/x1-x2 given two sets of points
What does a distance time graph show?
A distance-time graph shows the movement of an object with respect to time. The average slope between any two points on the graph is equal to the average velocity of the object between those two points.
