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 :))

Find the midpoint of the line using the midpoint formula.<br> Midpoint of AB:______

dimaraw [331]

Answer: MP=(1,1)

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})$

$MP= (\frac{-2+4}{2})(\frac{-3+5}{2})$ -2+4=2 -3+5=2

$MP= (\frac{2}{2})(\frac{2}{2})$ 2/2=1

$MP= (1,1)$
