A common form of a linear equation in the two variables x and y is y = mx + b,
\n" ); document.write( "where m and b are called constants. The origin of the name \"linear\" comes from the fact that the set of solutions of such an equation forms a straight line in the coordinate plane. In this particular equation, the constant m determines the slope or gradient of that line, and the constant term \"b\" determines the point at which the line crosses the y-axis, otherwise known as the y-intercept.\r

\n" ); document.write( "\n" ); document.write( "In math, the slope or gradient of a line describes its steepness, incline, or grade. A higher slope value indicates a steeper incline. \r
\n" ); document.write( "\n" ); document.write( "Slope is normally described by the fraction of the \"rise\" divided by the \"run\" between two points on a given line or linear equation in the form y = mx + b. \r
\n" ); document.write( "\n" ); document.write( "The rise is represented by (y2 − y1).\r
\n" ); document.write( "\n" ); document.write( "The run is represented by (x2 − x1).\r
\n" ); document.write( "\n" ); document.write( "The slope m of the line is found using the formula m = (y2 - y1)/(x2 - x1).\r
