Answer:
The expression
D = √(x2-x1)²+(y2-y1)
Distance between the two point is 8.06
Explanation:
Given two points in space (x1,y1) and (x2,y2). The distance between this two points is calculated using the expression
D = √(x2-x1)²+(y2-y1)²
Given two points, the expression which gives the distance between the two points is described using the above formula.
Given the points (5,1) and (9, -6)
x1 = 5, y1= 1, x2 = 9, y2 = -6
D = √(9-5)²+(-6-1)²
D = √4²+(-7)²
D = √16+49
D = √65
D = 8.06
