Graphing various kinds of lines

See also

In this brief article, we will discuss some miscellaneous important points to keep in mind about graphing lines. In graphing straight lines, it is important to keep in mind that any equation of the form ax + by = c, where a, b, and c are constants, will be a straight line (inversely, any straight line in a graph, is a graph of the aforementioned equation).

Keepin mind that the equation of the form y = 1 is always a straightforward horizontal line. Likewise, an equation of the form such as x = -8 is a vertical line through -8 on the x-axis (or whatever value input happens to take the place of the variable).

An intercept is simply a point at which a line crosses an axis. The x-intercept is the point at which a line crosses an x-intercept, and a y-intercept is a point at which a line crosses a y-axis.
