Question

(7.8). (-1,0)find the distance between the two points?

Answer 1

The distance between two points is computed as follows:

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

where (x1, y1) and (x2, y2) are the points of interest. In this case, the points are (7, 8) and (-1, 0). Replacing into the formula:

$d\text{ = }\sqrt{(-1-7)^2+(0-8)^2}=\sqrt{(-8)^2+(-8)^2}$$d=\sqrt{128}$
