Question

Which expression gives the distance between the points (5,1) and (9, -6)

Answer 1

Answer:

The expression

D = √(x2-x1)²+(y2-y1)

Distance between the two point is 8.06

Step-by-step 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

Answer 2

I believe you do 
$x^{2} - x /y^{2} - y$
