Introduction

In geometry, the distance between two parallel lines is a measure of the shortest distance between the two lines. This concept is crucial in various fields, including engineering, physics, and computer science. In this article, we will discuss how to find the distance between two parallel lines, using the given equations of the lines.

Understanding Parallel Lines

Parallel lines are lines that lie in the same plane and never intersect, no matter how far they are extended. The equations of parallel lines are in the form of ax + by = c, where a, b, and c are constants. The coefficients a and b determine the slope of the line, while the constant c determines the y-intercept.

Given Equations

The given equations of the parallel lines are:

  • 2x+5y=102x + 5y = 10
  • 2x+5y+6=02x + 5y + 6 = 0

Step 1: Rewrite the Equations

To find the distance between the parallel lines, we need to rewrite the equations in the standard form, which is ax + by = c. We can rewrite the second equation as:

2x+5y=−62x + 5y = -6

Step 2: Find the Distance

The distance between two parallel lines is given by the formula:

d=∣c1−c2∣a2+b2d = \frac{|c_1 - c_2|}{\sqrt{a^2 + b^2}}

where c1c_1 and c2c_2 are the constants in the two equations, and a and b are the coefficients of x and y.

Calculating the Distance

Substituting the values from the given equations, we get:

d=∣10−(−6)∣22+52d = \frac{|10 - (-6)|}{\sqrt{2^2 + 5^2}} d=∣10+6∣4+25d = \frac{|10 + 6|}{\sqrt{4 + 25}} d=1629d = \frac{16}{\sqrt{29}} d=1629×2929d = \frac{16}{\sqrt{29}} \times \frac{\sqrt{29}}{\sqrt{29}} d=162929d = \frac{16\sqrt{29}}{29}

Conclusion

In this article, we discussed how to find the distance between two parallel lines using their equations. We rewrote the equations in the standard form, and then used the formula to calculate the distance. The distance between the two parallel lines is 162929\frac{16\sqrt{29}}{29}.
