Distance Between Two Points Reviewer
and Interactive Calculator

Enter new data in the input box shown below.Then select Solve.
Point 1 ( x ₁ , y₁ )
Point 2 ( x ₂ , y₂ )

ANSWER : Distance, D =

---

Line Equation, x y + = 0 ; written in general form of the equation of a line and in its simpliest form.

---

Line Equation, y = x + ; written in standard form, also known as slope-intercept form.

---

Formula Recall

y = mx + b ; Equation of a line in slope form ---- Equation 1

---

mx - y + b = 0; re-writing equation 1 in the general form Ax + By + C = 0 --Equation 2

---

slope, m =
slope , m = (y₂ - y₁₎/ (x₂ - x₁) -- Equation 3

---

using point (x₂,y₂) and slope m,
substitutes its values in Equation 1

= * + b ; slope form ---- Equation 1

b =
