distance $=sqrt(106)$

The points are
$(2,-4) = color(blue)(x_1,y_1$

$(7,5) = color(blue)(x_2,y_2$

Distance is found using formula
distance $=sqrt((x_2-x_1)^2 +(y_2-y_1)^2$

distance $=sqrt((7-2)^2 +(5-(-4))^2$

$=sqrt((5)^2 +(9)^2$

$=sqrt((25+81)$

$=sqrt(106)$

What is the distance between (2,-4)(2,-4) and (7,5)(7,5)?
