Line segment line segment X Y has endpoints X negative 10 comma negative 1 and Y 5 comma 15 To find the y -coordinate of the point that divides the directed line segment in a ratio of 5 to 3 ratio, the formula y is equal to open paren the fraction with numerator A and denominator A plus b close paren times open paren y sub 2 minus y sub 1 close paren plus y sub 1 was used to find that y is equal to open paren the fraction with numerator 5 and denominator 5 plus 3 close paren times open paren 15 minus negative 1 close paren plus negative 1 What is the y -coordinate of the point that divides line segment x y into a ratio of 5 to 3 ratio?
