Answer:
[tex]\sqrt{17}[/tex]
Step-by-step explanation:
Calculate the length (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (0, 7)
d = [tex]\sqrt{(0+1)^2+(7-3)^2}[/tex]
= [tex]\sqrt{1^2+4^2}[/tex]
= [tex]\sqrt{1+16}[/tex]
= [tex]\sqrt{17}[/tex] ≈ 4.1 ( to 1 dec. place )
