Question

Find the distance detween the points -5 ,7 and(-1,3

Answer 1

1} Distance between -5 & 7

$| - 5 - 7| = | - 12| = 12$

.

2} Distance between -1 & 3

$| - 1 - 3| = | - 4| = 4$

Answer 2

Answer:

Step-by-step explanation:

Distance d = $\sqrt{(x_{1} -x_{2} )^{2} + (y_{1}-y_{2} )^{2} }$

x1 = -5

y1 = 7

x2 = -1

y2 = 3

d = $\sqrt{(-5--1)^{2} + (7-3)^{2} }$

d = $\sqrt{-4^{2} +4^{2} }$

d = $\sqrt{16 + 16}$

d = $\sqrt{32}$

d = 5.66
