The Formula
Variable Definitions
- d: The straight-line distance between the two points
- M: The midpoint — the point exactly halfway between the two points
- m: The slope — rise over run, rate of change of y with respect to x
- (x₁, y₁): The coordinates of the first point
- (x₂, y₂): The coordinates of the second point
Analyzing Points A(1, 2) and B(4, 6)
Find the distance, midpoint, slope, and line equation.
- Step 1: Identify points: A(1, 2), B(4, 6).
- Step 2: Distance: d = √((4-1)² + (6-2)²) = √(9 + 16) = √25 = 5.
- Step 3: Midpoint: M = ((1+4)/2, (2+6)/2) = (2.5, 4).
- Step 4: Slope: m = (6-2)/(4-1) = 4/3.
- Step 5: Line equation: y - 2 = (4/3)(x - 1), or y = (4/3)x + 2/3.
Frequently Asked Questions
What is a coordinate grid?
A coordinate grid (or coordinate plane) is a two-dimensional surface defined by a horizontal x-axis and vertical y-axis. Every point on the grid is identified by an ordered pair (x, y).
How do I find the distance between two points?
Use the distance formula: d = √((x₂-x₁)² + (y₂-y₁)²). This is derived from the Pythagorean theorem applied to the right triangle formed by the two points.
What is the midpoint formula?
The midpoint M between two points (x₁,y₁) and (x₂,y₂) is M = ((x₁+x₂)/2, (y₁+y₂)/2). It gives the coordinates of the point exactly halfway between them.
How do I find the slope of a line?
Slope m = (y₂ - y₁) / (x₂ - x₁), also written as rise/run. A positive slope means the line goes up from left to right; negative means it goes down.
What is the equation of a line through two points?
Use point-slope form: y - y₁ = m(x - x₁), where m is the slope. Substitute any of the two points and the calculated slope to get the equation.
Can I use this for three or more points?
This calculator works with two points. For three or more points, you can calculate pairwise distances, find centroids, or check collinearity using slopes.
