Help me with this!!!!

Answer:
5 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1 )^2 }[/tex]
with (x₁, y₁ ) = (6, 4) and (x₂, y₂ ) = (3, 8)
d = [tex]\sqrt{(3-6)^2+(8-4)^2}[/tex]
= [tex]\sqrt{(-3)^2+4^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]
= 5
