6x + 9y = 6
\n" ); document.write( "x + (3/2)y = 1
\n" ); document.write( "x = 1 - (3/2)y
\n" ); document.write( "---
\n" ); document.write( "2x = 2 - 3y
\n" ); document.write( "---
\n" ); document.write( "2x = 2 -3y
\n" ); document.write( "2(1 - (3/2)y) = 2 - 3y
\n" ); document.write( "2 - 3y = 2 - 3y
\n" ); document.write( "2 = 2
\n" ); document.write( "---
\n" ); document.write( "the two linear equations appear to describe the same line
\n" ); document.write( "---
\n" ); document.write( "check:
\n" ); document.write( "put in slope-intercept form:
\n" ); document.write( "9y = -6x + 6
\n" ); document.write( "y = (-2/3)x + 2/3
\n" ); document.write( "---
\n" ); document.write( "put in slope-intercept form:
\n" ); document.write( "2x = 2 - 3y
\n" ); document.write( "3y = -2x + 2
\n" ); document.write( "y = (-2/3)x + 2/3
\n" ); document.write( "---
