You can put this solution on YOUR website!
The general linear equation is: y = mx + b.
\n" ); document.write( "m = slope = change in 'y' divided by change in 'x' = the rise over the run
\n" ); document.write( ".
\n" ); document.write( "m =4, which is given
\n" ); document.write( ".
\n" ); document.write( "The y-intercept is the point (0,3). So when x=0, y=3.
\n" ); document.write( ".
\n" ); document.write( "y = 4x + 3
\n" ); document.write( ".
\n" ); document.write( "You can graph this to see how steep a slope of 4 looks.
\n" ); document.write( ".

\n" ); document.write( ".
\n" ); document.write( "Note
\n" ); document.write( "a) Positive slope always goes up from lower left to upper right.
\n" ); document.write( "b) Negative slope always goes down from upper left to lower right.
\n" ); document.write( "c) A horizontal line has slope = 0.
\n" ); document.write( "d) A vertical line has an undefined slope because you cannot divide by 0.
\n" ); document.write( ".
\n" ); document.write( "Done.
