Question

What is the distance between points (-3, -7) and (-7, -9)?

Answer 1

d=squareroot 20

Answer 2

\[distance=\sqrt{20}\]

Answer 3

i gotcha!

Answer 4

\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 5

The distance formula is \(d=\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}}\)
\( d = \sqrt{(-3+7)^{2} + (-7+9)^{2}}\)
\(d=\sqrt{(4)^{2} + (2)^{2}}\)
\(d=\sqrt{16 + 4}\)
\(d=\sqrt{20}\)

Answer 6

너무 단순해서
