$=sqrt(130$

$(-4,7) = color(blue)(x_1,y_1$

$(7, 4) = color(blue)(x_2,y_2$

The distance is calculated using formula:

Distance $=sqrt((x_1 - x_1)^2 + (y_2 - y_1)^2)$

$=sqrt((7 - (-4))^2 + (4- 7)^2)$

$=sqrt((7 + 4)^2 + (- 3)^2)$

$=sqrt((11)^2 + (- 3)^2)$

$=sqrt((121 + 9)$

$=sqrt(130$

What is the distance between (–4, 7)(–4, 7) and ( 7, 4) ( 7, 4) ?
