Question

what is the distance between (-7, 3) and (-2, 9)

Answer 1

Answer:

hey here is your solution

so pls mark it as brainliest

Step-by-step explanation:

now here let A=(-7,3)=(x1,y1)

B=(-2,9)=(x2,y2)

so now using distance formula

we get

d(A,B)=

$\sqrt{(x2 - x1)whole \: square} + (y2 - y1)whole \: square$

$= \sqrt[]{( - 2 - ( - 7)whole \: square + (9 - 3)whole \: square}$

$= \sqrt[]{( - 2 + 7)whole \: square + (6)whoe \: square}$

= under root of (5)whole square+(6) whole square

=under root of 25+61

=root 61 units

thus distance is root 61 units

Answer 2

Question:-

What is the distance between (-7 ,3) and (-2,9)

Solution:-

Distance

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

So, the distance will be

$\sqrt{ {( - 2 - ( - 7))}^{2} +(9 - 3)^{2} }$

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

$= \sqrt{25 + 36}$

$= \sqrt{61}$
