The area of a triangle with vertices (x 1, y 1 ), (x 2, y 2 ), and (x 3, y 3 )is represented by the formula on the right where the plus or minus symbol indicates that the appropriate sign should be chosen to yield a positive area. use determinants to find the area of the triangle whose vertices are (negative 9, 7 ), (4, 8 ), and (9, negative 9).
