Introduction

In mathematics, the concept of distance and equidistance plays a crucial role in various geometric and algebraic problems. One such problem involves finding an equation that represents a point (x,y){(x, y)} that is at the same distance from a given point (4,1){(4, 1)} as it is from the x-axis. This problem requires a deep understanding of the distance formula and the properties of points in a coordinate plane.

The Distance Formula

The distance formula is a fundamental concept in mathematics that calculates the distance between two points in a coordinate plane. Given two points (x1,y1){(x_1, y_1)} and (x2,y2){(x_2, y_2)}, the distance between them is given by the formula:

d=(x2x1)2+(y2y1)2{d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}}

This formula can be used to calculate the distance between any two points in a coordinate plane.

Equidistance from a Given Point and the X-Axis

To find an equation that represents a point (x,y){(x, y)} that is at the same distance from a given point (4,1){(4, 1)} as it is from the x-axis, we need to use the distance formula. Let's denote the distance from the point (x,y){(x, y)} to the x-axis as d1{d_1} and the distance from the point (x,y){(x, y)} to the given point (4,1){(4, 1)} as d2{d_2}. Since the point (x,y){(x, y)} is equidistant from the given point and the x-axis, we can set up the following equation:

d1=d2{d_1 = d_2}

Substituting the distance formula into this equation, we get:

(x0)2+(y0)2=(x4)2+(y1)2{\sqrt{(x - 0)^2 + (y - 0)^2} = \sqrt{(x - 4)^2 + (y - 1)^2}}

Simplifying this equation, we get:

x2+y2=(x4)2+(y1)2{x^2 + y^2 = (x - 4)^2 + (y - 1)^2}

Expanding the right-hand side of this equation, we get:

x2+y2=x28x+16+y22y+1{x^2 + y^2 = x^2 - 8x + 16 + y^2 - 2y + 1}

Simplifying this equation further, we get:

8x2y=15{8x - 2y = -15}

This is the equation that represents a point (x,y){(x, y)} that is at the same distance from the given point (4,1){(4, 1)} as it is from the x-axis.

Graphical Representation

To visualize the equation 8x2y=15{8x - 2y = -15}, we can graph it on a coordinate plane. The graph of this equation is a line that passes through the point (4,1){(4, 1)} and is perpendicular to the x-axis.
