Math Problem Statement

The coordinates of the endpoints of UV are U(1, -6) and V(11, 9). Point W is on UV and divides it such that UW:VW is 3:2. What are the coordinates of W? Write your answers as integers or decimals.

Solution

The problem states:

  • The coordinates of the endpoints of UVUV are U(1,6)U(1, -6) and V(11,9)V(11, 9).
  • Point WW is on UVUV and divides it such that the ratio UW:VW=3:2UW : VW = 3:2.

We need to find the coordinates of WW.

Solution Approach:

We can use the section formula. If a point divides a line segment in a ratio m:nm:n, the coordinates (x,y)(x, y) of the dividing point are given by:

x=mx2+nx1m+n,y=my2+ny1m+nx = \frac{m \cdot x_2 + n \cdot x_1}{m+n}, \quad y = \frac{m \cdot y_2 + n \cdot y_1}{m+n}

Where:

  • (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) are the coordinates of the endpoints of the line.
  • m:nm:n is the given ratio.

In this case:

  • (x1,y1)=(1,6)(x_1, y_1) = (1, -6) and (x2,y2)=(11,9)(x_2, y_2) = (11, 9),
  • The ratio m:n=3:2m:n = 3:2.

Let's now calculate the coordinates of WW. I'll do the math.
