According to the given data we have the following expression:

√(x2 – x1)2 + (y2 – yı)2

The equation above is used to calculate the distance between the two points x1 y1 and x2 y2.

Distance is represented by letter D.

So the formula to calculate the distance would be:

d=√(x2 – x1)2 + (y2 – yı)2

The distance formula calculates the distance between two points in the coordinate plane. If (x1, y1) and (x2, y2) are the two points in question, the distance d between these two points is √((y2-y1)^2 + (x2-x1)^2
