Non-collinear points are any group of three or more points that do not fall on the same straight line. More than two points in the group are needed for non-collinear points, since any two points can form a straight line. More »

An angle is formed by the union of two non-collinear rays that have a common endpoint. This endpoint is the vertex of the angle, and the two rays become the sides of this angle. These two rays can form different types of... More »

Non-coplanar points are any group of points that do not lie along the same geometrical plane. Points are considered coplanar if they lie along the same plane, and are often used to name that plane (e.g. plane ABCD). If a... More »

A linear function is graphed as a straight line and contains one independent variable and one dependent variable, whereas an exponential function has a rapid increase or decrease along a curved line in a graph. Linear fu... More »

Linear graphs represent the behavior of dependent variables that sit along a straight line with regard to independent variables, while nonlinear graphs represent variables that don't. Common functions that result in nonl... More »

A slope intercept form converter is an online tool that helps students determine the slope intercept form of the equation of a straight line. A student supplies the tool with the x and y coordinates of the line in the fo... More »

In mathematics, linear refers to an equation or function that is the equation of a straight line and takes the form y = mx + b, where "m" is equal to the slope, and "b" is equal to the y-intercept. Three features define ... More »
