Here we will show you how to find the distance between the points (5,8) and (-9,2) using a formula. In other words, you have the points (5,8) and (-9,2) 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 (5,8) and (-9,2) so it is easy to follow along:
(5,8) and (-9,2) = (x₁,y₁) and (x₂,y₂)
x₁ = 5
y₁ = 8
x₂ = -9
y₂ = 2
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 (5,8) and (-9,2), is as follows:
d = √(x₁ - x₂)² + (y₁ - y₂)²
The next step is to enter our points into the formula. When we enter (5,8) and (-9,2) into the formula, we get this:
d = √((5) - (-9))² + ((8) - (2))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 (5,8) and (-9,2):
d = √((5) - (-9))² + ((8) - (2))²
d = √(14)² + (6)²
d = √196 + 36
d = √232
d ≈ 15.2315
