These are part of our exam, i just want to share some questions with you..actually we are done with our exams..Find the coordinates of the point which divides the line segment from (-2,1) and (2,-3) in the ratio 3 to 4.

    i think it would be an internal division wherein the point from (-2,1) would be three parts of the whole segment form.

    of course, but you need to understand the problem first of what is asked?

    The length between the 2 points is 4sqrt(2) The point (x,y) will be (3/7)(4sqrt2) from (-2,1) and (4/7)(4sqrt2) from (2,-3) using the distance formula \[(x+2)^{2} + (y-1)^{2} = \frac{288}{49}\] \[(x-2)^{2} + (y+3)^{2} = \frac{512}{49}\] of which a solution is \[(-.2857, -.714)\]
