$sqrt377$

$color(blue)((-4,2)and (15,6)$

To find the distance between $2$ points

Use distance formula

$color(brown)(d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)$

Where

$color(red)(x_1=-4,y_1=2,x_2=15,y _2=6$

$rarrd=sqrt((15-(-4))^2+(6-2)^2)$

$rarrd=sqrt((19)^2+(4)^2$

$rarrd=sqrt(361+16)$

$color(green)(rArrd=sqrt377~~19.4$
