The equation of a line (also known as the slope-intercept form) generally shows y as a function of x, like this: The characteristics of a line can be conveyed through a mathematical formula. The slope of a vertical line is undefined because you don’t know whether it’s rising or falling it has no slope and is parallel to the y-axis.A horizontal line has a slope of 0 it neither rises nor falls and is parallel to the x-axis.A line with a positive slope rises from left to right (its right side is higher than its left), and its slope is greater than 0.A line with a negative slope falls from left to right (its left side is higher than its right), and its slope is less than 0.Then you subtract the x-coordinate of one point from the x-coordinate of the other point to get the denominator. The formula is just the ratio of the vertical distance between two points and the horizontal distance between those same two points. You subtract the y-coordinate of one point from the y-coordinate of the other point to get the numerator. The x and y values in the equation stand for the coordinates of two points on the line. The measure of the steepness of the line’s rising or falling is its slope. If a line isn’t parallel to one of the coordinate axes, it either rises or falls from the left-hand side of the coordinate plane to the right-hand side. M stands for midpoint and the x and y variables are the x and y coordinates of the line’s two endpoints. The formula to find the distance between A and B isįor calculating the midpoint coordinates of a line segment on the coordinate plane, you simply apply the midpoint formula: The intersection of the x- and y-axes forms four quadrants on the coordinate plane.Īll points in Quadrant I have a positive x value and a positive y value.Īll points in Quadrant II have a negative x value and a positive y value.Īll points in Quadrant III have a negative x value and a negative y value.Īll points in Quadrant IV have a positive x value and a negative y value.Īll points along the x-axis have a y value of 0.Īll points along the y-axis have an x value of 0.Īssume you have two points, A (x 1, y 1) and B (x 2, y 2), on a line. For example, the ordered pair (2, 3) has a coordinate point located two units to the right of the origin along the horizontal (x) number line and three units up on the vertical (y) number line. You can identify any point on the coordinate plane by its coordinates, which designate the point’s location along the x- and y-axes. Slope: Slope measures how steep a line is and is commonly referred to as the rise over the run. Y-intercept: The value of y where a line, curve, or some other function crosses the y-axis. The x-intercept is often the solution or root of an equation. X-intercept: The value of x where a line, curve, or some other function crosses the x-axis.

The horizontal (x) coordinate is always listed first, and the vertical (y) coordinate is listed second. Ordered pair: Also known as a coordinate pair, this duo is the set of two values that expresses the distance a point lies from the origin. Origin: The origin is the point (0, 0) on the coordinate plane. The y value of a point’s coordinate is listed second in its ordered pair.

Numbers increase in value going up from the origin and decrease in value going down. Its values start at the origin, which has a value of 0. Y-axis: The y-axis is the vertical axis (number line) on a coordinate plane. The x value of a point’s coordinate is listed first in its ordered pair. Numbers increase in value to the right of the origin and decrease in value to the left. The values start at the origin, which has a value of 0. X-axis: The x-axis is the horizontal axis (number line) on a coordinate plane. The coordinate of any particular point is the set of numbers that identifies the location of the point, such as (3, 4) or (x, y). In a coordinate plane, any point can be represented by a pair of numerical coordinates. These pairs of numbers represent the points’ distances from an origin on perpendicular axes. Coordinate geometry involves working with points on a graph that is known as the Cartesian coordinate plane. This perfectly flat surface has a system that allows you to identify the position of points by using pairs of numbers.
