On a coordinate plane, a line is drawn from point k to point j. point k is at (9, 2) and point j is at (1, negative 10). what is the x-coordinate of the point that divides the directed line segment from k to j into a ratio of 1: 3? x = (startfraction m over m + n endfraction) (x 2 minus x 1) + x 1 –1 3 7 11
