\r\n" );
document.write( "The slope formula, as you wrote it, works ALWAYS, for any function, not necessary linear.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "If the function is linear, then the slope is the constant value along the entire straight line.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The slope formula is the same, and it defines the slope \"m\" of the straight line y = mx + c.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "If the relationship is direct proportionality y = kx, it means that the straight line passes through the origin of the coordinate system.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The general formula for the slope works in this case too, and it defines the slope, which is exactly the coefficient proportionality \"k\" in this case.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Notice that in the last case   =  = k.\r\n" );
document.write( "\r\n" );
