slope is change in y over change in x
\n" ); document.write( ":
\n" ); document.write( "(18-6)/(8-4)=12/4=3
\n" ); document.write( ":
\n" ); document.write( "so slope is 3
\n" ); document.write( ":
\n" ); document.write( "use point slope formula....using slope 3 and either given point...I am using (4,6)
\n" ); document.write( ":
\n" ); document.write( "y-6=3(x-4)
\n" ); document.write( ":
\n" ); document.write( "y-6=3x-12
\n" ); document.write( ":
\n" ); document.write( "y=3x-6 in slope intercept form
\n" ); document.write( "
\n" );
