Question

What formula can be used to find the length of a segment in a coordinate plane? and how would u say it in a sentence form ? e-e

Answer 1

The distance formula

Answer 2

\[\Large d=\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]

Answer 3

for a segment AB
AB^2 = Δx^2 + Δy^2
so
AB = squareroot(Δx + Δy)
Δx(Delta x) is always the difference in two values x1 and x2
so in this case
Δx = xA - xB
and
Δy = yA - yB

Answer 4

The distance formula is derived from the Pythagorean theorem. To find the distance between two points (x1,y1) and (x2,y2),
