Question

Silvia is trying to calculate the distance between point A(2, 6) and point B(5, 1). Which of the following expressions will she use?

answers: square root of the quantity of 5 minus 2 all squared plus 1 minus 6 all squared
square root of the quantity of 5 minus 1 all squared plus 2 minus 6 all squared
square root of the quantity of 6 minus 5 all squared plus 2 minus 1 all squared
square root of the quantity of 5 minus 6 all squared plus 1 minus 2 all squared

Answer 1

distance formula is
D=$\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$

(x,y)
(2,6)
(5,1)
x1=2
y1=6
x2=5
y2=1

D=$\sqrt{(5-2)^{2}+(1-6)^{2}}$


answer is first one

Answer 2

Answer:

answer is first one

Step-by-step explanation:

distance formula is

D= \sqrt{(x2-x1)^{2}+(y2-y1)^{2}}  

(x,y)

(2,6)

(5,1)

x1=2

y1=6

x2=5

y2=1

D= \sqrt{(5-2)^{2}+(1-6)^{2}}
