Answer 1

Answer:

The answer is $\sqrt{61}$

.

Step-by-step explanation:

The distance formula:

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

.

☆All we need to do is plug in!

$d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{( - 1 - 4) ^{2} + ( - 9 - ( - 3))^{2} } \\ d = \sqrt{( - 5)^{2} + ( - 6) ^{2}} \\ d = \sqrt{25 + 36 } \\ d = \sqrt{61}$
