Find the distance between each pair of points

densk [106]

Answer:

Use Distance Formula

Step-by-step explanation:

You can find the distance between two points by using the distance formula which by definition is $\sqrt{(x_2-x_1 )^2+(y_2-y_1)^2 }$

For example take question 3. Plug your point values in to find the distance

Point 1 is (-1, 8)

Point 2 is (-3, -2)

You equation would look like:

$\sqrt{(-3-(-1))^2+(-2-8)^2}$

This simplifies to $\sqrt{(-2)^2+(-10)^2}$

= $\sqrt{4+100}$

= $\sqrt{104}$

= $\sqrt{2(2)(26)}$

= $2\sqrt{26}$

That is the distance between the points (-1, 8) and (-3, -2)
