What is the length of line segment AB, given A(5,-2) and B(-3,-4). Topic: Math 1 Answer | Add Yours beckden | High School Teacher | (Level 1) Educator Posted on December 17, 2011 at 9:46 AM The distance formula is `d=sqrt((x_1-x_2)^2+(y_1-y_2)^2)` So `d=sqrt((5-(-3))^2+(-2-(-4))^2)=sqrt(8^2+6^2)=sqrt(64+36)=sqrt(100)=10` So the answer is 10.
