Answer:
≈ 3.6 units
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (3, 7)
d = [tex]\sqrt{(3-1)^2+(7-4)^2}[/tex]
= [tex]\sqrt{2^2+3^2}[/tex]
= [tex]\sqrt{4+9}[/tex]
= [tex]\sqrt{13}[/tex] ≈ 3.6 units ( to 1 dec. place )
