9x -4y = 36
\n" ); document.write( ".
\n" ); document.write( "Get the above into slope-intercept form: y = m*x + b
\n" ); document.write( ".
\n" ); document.write( "-4y = -9x +36
\n" ); document.write( "y = 9/4*x -9
\n" ); document.write( ".
\n" ); document.write( "9/4 = slope
\n" ); document.write( "(0,-9) = y-intercept
\n" ); document.write( ".
\n" ); document.write( "To find the x-intercept, set y = 0 and solve for x.
\n" ); document.write( ".
\n" ); document.write( "0 = 9/4*x -9
\n" ); document.write( "-9/4*x = -9
\n" ); document.write( "cross multiply
\n" ); document.write( "-9*x = -9*4
\n" ); document.write( "-9*x = -36
\n" ); document.write( "x = 4
\n" ); document.write( "which defines the x-intercept: (4,0)
\n" ); document.write( ".
\n" ); document.write( "With two points, you can draw a line.
