Write an algebraic expression for the word expression the quotient of c and 8

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2
