The endpoints of the line ST are S(-1, -3) and T(5, -7). What is its length?

using the formula d=√(y1-y2)^2+(x1-x2)^2

A. 4√13 units
B. 2√13 units
C. 2√52 units
D. 4√52 units

Answer 1

You've got the formula, plug in the numbers:
Let S(-1,-3) be \(x_1, y_1\)
Let T(5,-7) be \(x_2,y_2\)

\[d = \sqrt{(-3-(-7))^2 + (-1-5)^2}\]
