You can put this solution on YOUR website!
k is the slope of the line. It is a number. If it is positive the line rises from left to right. If it is negative it falls from left to right. If k=0 then the line is horizontal. If the line is vertical then the slope is undefined.
\n" ); document.write( "Here is a graph of a line in which k=3.
\n" ); document.write( "y=3x
\n" ); document.write( "If you a table for x and y here is what you get:
\n" ); document.write( "x y
\n" ); document.write( "3 9
\n" ); document.write( "2 6
\n" ); document.write( "1 3
\n" ); document.write( "0 0
\n" ); document.write( "-1 -3
\n" ); document.write( "-2 -6
\n" ); document.write( "-3 -9
\n" ); document.write( ".
\n" ); document.write( "Get a piece of graph paper and put a dot on the paper for each value for x,y in the table. Connect the dots. Now you have a line with a slope of 3 like the one below.
