Find an equation of the line that passes through the point (3, 5) and is perpendicular to the line
\n" ); document.write( "8x + 9y − 4 = 0.
\n" ); document.write( "---
\n" ); document.write( "y = (-8x+4)/9
\n" ); document.write( "Slope of that line: -8/9
\n" ); document.write( "-----
\n" ); document.write( "Slope of perpendicular line: 9/8
\n" ); document.write( "---
\n" ); document.write( "Form: y = mx + b
\n" ); document.write( "Sustitute for y,x,and m; Solve for \"b\":
\n" ); document.write( "5 = (9/8)3 + b
\n" ); document.write( "40/8 = 27/8 + b
\n" ); document.write( "b = 13/8
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "y = (9/8)x + (13/8)
