Find the length of a segment with endpoints at (1,-2) and (-4,-4)
Paha777 [63]

Call (1,-2) for point A and (-4, -4) for point B

Use the distance formula AB = d(A, B) = \sqrt{(x_{B} - x_{A})^2 + (y_{B} - y_{A})^2}

Insert values for x_{B}, x_{A}, y_{B} and y_{A}

AB = \sqrt{(-4 - 1)^2 + (-4 - (-2))^2}\\= \sqrt{(-4 - 1)^2 + (-4 + 2)^2}\\= \sqrt{(-5)^2 + (-2)^2}\\= \sqrt{25 + 4}\\= \sqrt{29}
