What is the distance between the points (-3,-2) and (6, 10)?
Alja [10]

Answer:

The distance between (-3,-2) and (6, 10) =15

Step-by-step explanation:

The distance between the two points having given coordinates can be find by using the distance formula.

i.e  Distance= \sqrt{(x_2-x_1)+(y_2-y_1)}

For the given coordinates (-3,-2) and (6, 10)  the distance between the two points is :

Distance = \sqrt{(6-(-3))^2+(10-(-2))^2} \\=\sqrt{(6+3)^2+(10+2)^2}\\ =\sqrt{9^2+12^2}\\ =\sqrt{81+144} \\=\sqrt{225} \\=15
