Solution

1. Break Down the Problem

We need to find coordinates (x,y)(x, y) such that the distance between the points (2p1,3q+2)(2p - 1, 3q + 2) and (p+3,2q1)(p + 3, 2q - 1) is equal to the distance between (p,q)(p, q) and (x,y)(x, y).

2. Relevant Concepts

The distance dd between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is given by the formula: d=(x2x1)2+(y2y1)2 d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

3. Analysis and Detail

  1. Calculate the distance between (2p1,3q+2)(2p - 1, 3q + 2) and (p+3,2q1)(p + 3, 2q - 1):

    • Let:
      • (x1,y1)=(2p1,3q+2)(x_1, y_1) = (2p - 1, 3q + 2)
      • (x2,y2)=(p+3,2q1)(x_2, y_2) = (p + 3, 2q - 1)
    • The distance d1d_1 is: d1=((p+3)(2p1))2+((2q1)(3q+2))2 d_1 = \sqrt{((p + 3) - (2p - 1))^2 + ((2q - 1) - (3q + 2))^2}
    • Simplifying: d1=(p+32p+1)2+(2q13q2)2 d_1 = \sqrt{(p + 3 - 2p + 1)^2 + (2q - 1 - 3q - 2)^2} d1=(p+4)2+(q3)2 d_1 = \sqrt{(-p + 4)^2 + (-q - 3)^2} d1=(p4)2+(q+3)2 d_1 = \sqrt{(p - 4)^2 + (q + 3)^2}
  2. Let the distance between (p,q)(p, q) and (x,y)(x, y) be d2d_2:

    • The distance d2d_2 is: d2=(xp)2+(yq)2 d_2 = \sqrt{(x - p)^2 + (y - q)^2}
  3. Set the distances equal: (p4)2+(q+3)2=(xp)2+(yq)2 \sqrt{(p - 4)^2 + (q + 3)^2} = \sqrt{(x - p)^2 + (y - q)^2}

    • Squaring both sides gives: (p4)2+(q+3)2=(xp)2+(yq)2 (p - 4)^2 + (q + 3)^2 = (x - p)^2 + (y - q)^2

4. Verify and Summarize

To find (x,y)(x, y) that satisfies this, we observe:

This equation represents a geometric circle centered at (4,3)(4, -3) with radius equal to the distance from (p,q)(p, q) to (4,3)(4, -3). The coordinates (x,y)(x, y) lie on this circle.

Final Answer

Thus, the coordinates (x,y)(x, y) satisfy the equation: (xp)2+(yq)2=(p4)2+(q+3)2 (x - p)^2 + (y - q)^2 = (p - 4)^2 + (q + 3)^2 This describes a locus of points (x,y)(x, y) for any given (p,q)(p, q).

To find specific coordinates (x,y)(x, y) would require additional information or constraints.
