find the distance and the midpoint of the line segment with endpoints (-1,4) and (-5,3)

i already know the answer i just need an explanation

Answer:

see explanation

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1,4) and (x₂, y₂ ) = (- 5, 3)

d = [tex]\sqrt{(-5+1)^2+(3-4)^2}[/tex]

  = [tex]\sqrt{(-4)^2+(-1)^2}[/tex]

  = [tex]\sqrt{16+1}[/tex] = [tex]\sqrt{17}[/tex] ≈4.12 ( to 2 dec. places )

To find the midpoint use the midpoint formula

[0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

Using the same points as above then

midpoint = [0.5(- 1- 5), 0.5(4 + 3 ) ] = [0.5(- 6), 0.5(7) ] = (- 3, 3.5 )
