Find a relationship between x and y such that (x,y) is equidistant from the two points. (4,-1),(-3,5)

To find a relationship between \( x \) and \( y \) such that the point \( (x, y) \) is equidistant from the two given points \( (4, -1) \) and \( (-3, 5) \), we can use the concept that the distance between two points in the plane is given by the distance formula.

### Step 1: Distance Formula
The distance between two points \( (x_1, y_1) \) and \( (x_2, y_2) \) is given by:

\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]

### Step 2: Apply the Distance Formula
Let \( (x, y) \) be the point that is equidistant from \( (4, -1) \) and \( (-3, 5) \). This means the distance from \( (x, y) \) to \( (4, -1) \) must equal the distance from \( (x, y) \) to \( (-3, 5) \). Thus, we have the following equation:

\[
\sqrt{(x - 4)^2 + (y + 1)^2} = \sqrt{(x + 3)^2 + (y - 5)^2}
\]

### Step 3: Eliminate the Square Roots
To eliminate the square roots, square both sides of the equation:

\[
(x - 4)^2 + (y + 1)^2 = (x + 3)^2 + (y - 5)^2
\]

### Step 4: Expand Both Sides
Now, expand both sides of the equation:

\[
(x^2 - 8x + 16) + (y^2 + 2y + 1) = (x^2 + 6x + 9) + (y^2 - 10y + 25)
\]

### Step 5: Simplify the Equation
Cancel out the \( x^2 \) and \( y^2 \) terms (since they appear on both sides):

\[
-8x + 16 + 2y + 1 = 6x + 9 - 10y + 25
\]

Combine like terms:

\[
-8x + 2y + 17 = 6x - 10y + 34
\]

### Step 6: Rearrange Terms
Move all terms involving \( x \) and \( y \) to one side:

\[
-8x - 6x + 2y + 10y = 34 - 17
\]

Simplify:

\[
-14x + 12y = 17
\]

### Step 7: Final Equation
Divide the entire equation by 2 to simplify it:

\[
-7x + 6y = \frac{17}{2}
\]

Thus, the relationship between \( x \) and \( y \) such that the point \( (x, y) \) is equidistant from the points \( (4, -1) \) and \( (-3, 5) \) is:

\[
-7x + 6y = \frac{17}{2}
\]

This is the equation of the perpendicular bisector of the line segment joining the two points.
