According to Wolfram|Alpha, there are various mathematical equations that produce a graph in the shape of a heart. A simple example is the following equation: r(?) = 1 - sin(?), which produces a curve called a cardioid, meaning "heart-shaped."

To graph linear inequalities, start by drawing the line in the same fashion as you would with a linear equation. A linear inequality has many solutions that can lie above or below the line described by the expression.

The parent function for the linear equation is y = x. In general terms, the parent function provides a template for the range and the domain, which holds true for other equations within the family.

The simplest way to graph a quadratic equation is to substitute an array of values for x in the equation and solve for y in each case to obtain several (x,y) coordinates. After obtaining the coordinates, they can be plotted on graph paper along the x-y axis to form a parabolic curve that is typical

A linear inequality is similar to a linear equation; however, where a linear equation has an equals sign, a linear inequality uses an inequality symbol. Inequality symbols include (greater than),

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 nonlinear graphs include quadratic, cubic and exponential functions as well as funct

The Monterey Institute explains that the graph of a linear inequality has a shaded region and that a set of ordered points (x, y) may be located within or outside of the shaded region. To find the values of x and y that satisfy an inequality, one must obtain a pair of ordered points within the regio

A linear factor is the return on an asset in relation to a limited number of factors. A linear factor is mostly written in the form of a linear equation for simplicity.

Graphs are beneficial because they summarize and display information in a manner that is easy for most people to comprehend. Graphs are used in many academic disciplines, including math, hard sciences and social sciences. They make appearances in corporate settings, serving as useful tools to convey

The graph of a linear equation forms a straight line, while a non-linear equation's graph does not form a straight line.Most equations can be graphed on a Cartesian coordinate plane using the variables x and y.
