To graph a math equation, acquire some graphing paper, draw x and y axes, and decide whether the equation is linear or non-linear. Approach the problem by finding the slope of the linear equation or using a table for a non-linear one.

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."

Find the slope of the line (m), and the place where the line crosses the y-axis, known as the y-intercept (b), to write the equation in slope-intercept form, y = mx + b. Use the equation to find the y value for any x on that line.

A line graph connects points of data with line segments. Line graphs represent how data changes in value over time or some other form of measurement.

To make a line graph there needs to be an X-axis, which is horizontal, and a Y-axis, which is vertical. The two axis represent different sets of data so the data is required too. The easiest way to make a line graph is using a spreadsheet like Excel.

Use the titles of the vertical and horizontal axes of a line graph to understand the plotted points on it. The horizontal axis reflects an independent variable, such as time elapsed or occurrences of an event, while the vertical axis reflects the effect of that variable on a different factor.

To find a line's equation, identify two of the points through which the line passes, and then use the "x" and "y" coordinates to find the slope of the line, or the rate at which it climbs or falls. Use the slope to find the line's intersection with the y-axis.

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 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
