Explaination :
Here we would be using distance formula to calculate the distance between those two points.
★ Points are,
★ Distance Formula :
- [tex]\huge \large \boxed{\sf{{d \: = \: \sqrt{(x _{2} - x _{1}) {}^{2} \: + \: (y _{2} - y _{1}) {}^{2} }}}} \: \red\bigstar[/tex]
★ We have :
x1 = 3
x2 = -2
y1 = 9
y2 = 4
★ Substituting the values :
Additional Information :
Centroid of a triangle :-
- [tex]\boxed{ \sf{Centroid \: = \: \dfrac{x_1 \: + \: x_2 \: + \: x_3}{3} }} \: \pink\bigstar[/tex]
Midpoint of two points:-
- [tex]\boxed{ \sf{M \: = \: \dfrac{x_1 \: + \: x_2 }{2} \: , \: \dfrac{y_1 \: + \: y_2 }{2}}} \: \pink\bigstar[/tex]
