• Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (5, 1)

Point (9, -6)

Step 2: Identify

x₁ = 5, x₂ = 9

y₁ = 1, y₂ = -6

Step 3: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

1. Substitute in points [DF]:                    $\displaystyle d = \sqrt{(5-9)^2+(1+6)^2}$

Answer 2

Here,

two points are (5,1) and (9,-6)

So,

x1=5

x2=9

y1=1

y2= -6

we know that,

Distance formula:- $\bold{D=\sqrt{(x_2 - x_1 )^2+(y_2 - y_1)^2} }$

According to the question,

Distance between (5,1) and (9,-6)

$\bold{D=\sqrt{(5-9)^2+(1-\{-6\})^2} }$

$\bold{D=\sqrt{(5-9 )^2+(1+6)^2} }$

so,

option C is correct..
