slope intercept form is
\n" ); document.write( "first 2y=-3x+5
\n" ); document.write( "y=(-3/2)x+2.5
\n" ); document.write( "The slope is -1.5
\n" ); document.write( "\"graph%28300%2C300%2C-5%2C5%2C-5%2C5%2C-1.5x%2B2.5%29\"
\n" ); document.write( "The x-intercept is where y=0 and is 1.5x=2.5, x=5/3
\n" ); document.write( "The y-intercept is where x=0 and is y=2.5
\n" ); document.write( "the acute angle made has a tangent of 2.5/(5/3)=1.5
\n" ); document.write( "arc tan (1.5)=56.31 deg
\n" ); document.write( "the obtuse angle is the supplement or 123.69 deg
\n" ); document.write( "
