Here we will show you how to find the distance between the points (-2,4) and (5,8) using a formula. In other words, you have the points (-2,4) and (5,8) 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 (-2,4) and (5,8) so it is easy to follow along:
(-2,4) and (5,8) = (x₁,y₁) and (x₂,y₂)
x₁ = -2
y₁ = 4
x₂ = 5
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 (-2,4) and (5,8), is as follows:
d = √(x₁ - x₂)² + (y₁ - y₂)²
The next step is to enter our points into the formula. When we enter (-2,4) and (5,8) into the formula, we get this:
d = √((-2) - (5))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 (-2,4) and (5,8):
d = √((-2) - (5))² + ((4) - (8))²
d = √(-7)² + (-4)²
d = √49 + 16
d = √65
d ≈ 8.0623
