$=color(blue)(7$

$(3,7) = color(blue)((x_1 , y_1))$

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

Distance is calculated using formula:

distance $=sqrt((x_2-x_1)^2 +(y_2-y_1)^2$

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

$=sqrt((-7)^2 +(0)^2$

$=sqrt((49)$

$=color(blue)(7$

What is the distance between (3,7)(3,7) and (–4, 7) (–4, 7) ?
