What is the distance between the following points?

timama [110]

Answer:

D. d = $\sqrt{58}$

Step-by-step explanation:

Use the distance formula: d = $\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2} }$

The two points are (6, -2) and (3, -9)

Plug the values into the formula:

d = $\sqrt{(3 - 6)^{2}+ (-9 + 2)^{2} }$

Simplify

d = $\sqrt{(-3)^{2}+ (-7)^{2} }$

d = $\sqrt{9+ 49 }$

d = $\sqrt{58}$

I hope this helps :))
