Distance between the points (8,-4) and (-7,8)

Distance between (8,-4) and (-7,8)

Here we will show you how to find the distance between the points (8,-4) and (-7,8) using a formula. In other words, you have the points (8,-4) and (-7,8) 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 (8,-4) and (-7,8) so it is easy to follow along:

(8,-4) and (-7,8) = (x₁,y₁) and (x₂,y₂)

x₁ = 8
y₁ = -4
x₂ = -7
y₂ = 8

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 (8,-4) and (-7,8), is as follows:

d = √(x₁ - x₂)² + (y₁ - y₂)²

The next step is to enter our points into the formula. When we enter (8,-4) and (-7,8) into the formula, we get this:

d = √((8) - (-7))² + ((-4) - (8))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 (8,-4) and (-7,8):

d = √((8) - (-7))² + ((-4) - (8))²

d = √(15)² + (-12)²

d = √225 + 144

d = √369

d ≈ 19.2094
