lilla On a coordinate plane, point J is located at (-1, -2) and point K is located at (8, 10). What is the distance, in units fr

Talja [164]

Using the distance formula;

$|d|=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}$

From the points given:

x₁=-1 y₁=-2 x₂=8 y₂=10

substitute the values into the formula;

$|d|=\sqrt[]{(8+1)^2+(10+2)^2}$ $=\sqrt[]{9^2+12^2}$ $=\sqrt[]{81+144}$

$=\sqrt[]{225}$ $=15$

The distance is 15 units.
