And the coefficient of elasticity, calculated by the midpoint formula is -40/18.2 = -2.2 We are coming up with a different and higher value for elasticity than we did with the midpoint formula.

Line Segments and Midpoints. This lesson is on the midpoint formula. Now, in order to understand what the formula is, it's probably best to know what a midpoint itself is.

The formula for the midpoint of a line segment will tell you how to find the middle of any line segment on the x, y plane.

The error is less than 1 percent using the midpoint formula; it was 7 percent using the usual formula. Back to elasticity UPJ Economics Department Last modified: Sat Oct 12 13:11:14 1996. 1  the usual formula is dependent on which value is taken as the new value and which is taken as the old value.

1 The midpoint formula helps us find the point that is in the exact middle of any line segment. 2  If we know the endpoints of the line segment, then the midpoint has the coordinates given by this formula. 3  All this is really is the average, or the middle, of the x-coordinates, and the average of the y s as well.

Midpoint formula for elasticity. The coefficient of elasticity is defined as the percentage change in quantity demanded divided by the percentage change in price. The first step is to find percentage changes. The percentage change in any variable X is.

The Midpoint Formula: Definition of Midpoint. The Midpoint formula is used when you need the point that is exactly between two other points. The midpoint formula is applied when you need to find a line that bisects a specific line segment. Essentially, the 'middle point' is called the midpoint. Midpoint is a give away with its name.

Implementing this is straightforward. In our previous example: The percentage change in price, caluclated by the midpoint formula would be (12 - 10) / 11 = 2/11 = 18.2 percent since the average price is 11. The percentage change in quantity, calculated bye the midpoint formula would be (20 - 30) / 25 = -10/25 = -40 percent since the average quantity is 25.

How about this: find the midpoint between the two points (-5, 3) (-1, -3). We could use the formula by calling the first x, x 1, the second one, x 2. Do the same thing with the y s, and substitute the values in like so.

To quickly review what we've learned: 1  The midpoint formula helps us find the point that is in the exact middle of any line segment. 2  If we know the endpoints of the line segment, then the midpoint has the coordinates given by this formula.
