Find an equation of the line that passes through the given point and is perpendicular to the given line. Write the equation in slope-intercept form.
\n" ); document.write( "(8, −2), 7x = 9y − 8
\n" ); document.write( "***
\n" ); document.write( "Equation of a line: y=mx+b, m=slope, b=y-intercept
\n" ); document.write( "7x = 9y − 8
\n" ); document.write( "9y=7x+8
\n" ); document.write( "y=7x/9+8/9
\n" ); document.write( "slope of given line, m=7/9
\n" ); document.write( "slope of perpendicular line=-9/7 (negative reciprocal)
\n" ); document.write( "Equation:
\n" ); document.write( "y=-9x/7+b
\n" ); document.write( "solve for b using given coordinates(8,-2) on the line
\n" ); document.write( "-2=-9*8/7+b
\n" ); document.write( "-2=-72/7+b
\n" ); document.write( "b=58/7
\n" ); document.write( "Equation of perpendicular line:
