Here we will show you how to find the distance between the points (-4,-2) and (9,0) using a formula. In other words, you have the points (-4,-2) and (9,0) 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 (-4,-2) and (9,0) so it is easy to follow along:
(-4,-2) and (9,0) = (x₁,y₁) and (x₂,y₂)
x₁ = -4
y₁ = -2
x₂ = 9
y₂ = 0
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 (-4,-2) and (9,0), is as follows:
d = √(x₁ - x₂)² + (y₁ - y₂)²
The next step is to enter our points into the formula. When we enter (-4,-2) and (9,0) into the formula, we get this:
d = √((-4) - (9))² + ((-2) - (0))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 (-4,-2) and (9,0):
d = √((-4) - (9))² + ((-2) - (0))²
d = √(-13)² + (-2)²
d = √169 + 4
d = √173
d ≈ 13.1529
