Question

Find the distance between the following pairs of points.

$(7,0)$ and $(-8,0)$

Answer 1

Take points $A(7,0)$ and $B(-8,0)$

To find the distance between two point $A(x_1,y_1)$ and $B(x_2,y_2)$, distance formula is used which is given by:

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

So, $AB=\sqrt{(7-(-8){)}^2+(0-0{)}^2}$

$=\sqrt{(225+0)}$

$=\sqrt{\left(225\right)}$

$=15$.
