Here we will show you how to find the distance between the points (-8,9) and (5,-3) using a formula. In other words, you have the points (-8,9) and (5,-3) 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 (-8,9) and (5,-3) so it is easy to follow along:
(-8,9) and (5,-3) = (x₁,y₁) and (x₂,y₂)
x₁ = -8
y₁ = 9
x₂ = 5
y₂ = -3
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 (-8,9) and (5,-3), is as follows:
d = √(x₁ - x₂)² + (y₁ - y₂)²
The next step is to enter our points into the formula. When we enter (-8,9) and (5,-3) into the formula, we get this:
d = √((-8) - (5))² + ((9) - (-3))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 (-8,9) and (5,-3):
d = √((-8) - (5))² + ((9) - (-3))²
d = √(-13)² + (12)²
d = √169 + 144
d = √313
d ≈ 17.6918
