What is the distance between coordinates (-6.25,5) and (-3.75,2)

Oksi-84 [34.3K]

Answer:

$\sqrt{15.25}$

Step-by-step explanation:

To find the distance, we can use the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ when the given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the points (-6.25,5) and (-3.75,2)

$d=\sqrt{(-6.25-x_1)^2+(5-y_1)^2}\\d=\sqrt{(-6.25-(-3.75))^2+(5-2)^2}\\d=\sqrt{(-6.25+3.75)^2+(5-2)^2}\\d=\sqrt{(-2.5)^2+(3)^2}\\d=\sqrt{6.25+9}\\d=\sqrt{15.25}$

Therefore, the distance between the two coordinates is $\sqrt{15.25}$ , or approximately 3.91.

I hope this helps!
