Distance between the points (-1,9) and (5,-1)

Distance between (-1,9) and (5,-1)

Here we will show you how to find the distance between the points (-1,9) and (5,-1) using a formula. In other words, you have the points (-1,9) and (5,-1) on a two-dimensional graph with an x-axis and a y-axis, and you want to find the distance between the two points.

We start by labeling and coloring the points (-1,9) and (5,-1) so it is easy to follow along:

(-1,9) and (5,-1) = (x₁,y₁) and (x₂,y₂)

x₁ = -1
y₁ = 9
x₂ = 5
y₂ = -1

Next, we will show you the formula you can use to calculate the distance between two points. The formula to calculate the distance (d) between two points, such as (-1,9) and (5,-1), is as follows:

d = √(x₁ - x₂)² + (y₁ - y₂)²

The next step is to enter our points into the formula. When we enter (-1,9) and (5,-1) into the formula, we get this:

d = √((-1) - (5))² + ((9) - (-1))²

All we need to do now is solve the equation above. Here is the math and the answer to the distance (d) between the points (-1,9) and (5,-1):

d = √((-1) - (5))² + ((9) - (-1))²

d = √(-6)² + (10)²

d = √36 + 100

d = √136

d ≈ 11.6619
