On a number line, the directed line segment from Q to S has endpoints Q at –2 and S at 6. Point R partitions the directed line segment from Q to S in a 3:2 ratio. Rachel uses the section formula to find the location of point R on the number line. Her work is shown below. Let m = 3, n = 2, x1 = –2, and x2 = 6. R = StartFraction m x 2 + n x 1 Over m + n EndFraction R = StartFraction 3 (6) + 2 (negative 2) Over 3 + 2 EndFraction What is the location of point R on the number line?
