Given
\n" ); document.write( "Point (x, y)=(4,-8)
\n" ); document.write( "Slope = m = 8/9\r
\n" ); document.write( "\n" ); document.write( "Equation of the line slope-intercept form
\n" ); document.write( "y=mx+b
\n" ); document.write( "Put the given values of point and slope in above equation in order to know the y-intercept
\n" ); document.write( "-8=(8/9)(4)+b
\n" ); document.write( "-8=32/9+b
\n" ); document.write( "-8-32/9=b
\n" ); document.write( "(-72-32)/9=b
\n" ); document.write( "b=-104/9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y-intecept = b = -104/9\r
\n" ); document.write( "\n" ); document.write( "Again put the values of slope and y-intercept in the equation of the line slope-intercept form
\n" ); document.write( "y=8/9(x)+(-104/9)
\n" ); document.write( "y=8x/9-104/9
\n" ); document.write( "Above equation is required equation of the line.\r
