Find the slope and y-intercept of the line that is perpendicular to y=3x−4 and passes through the point (6,−7)
\n" ); document.write( "**
\n" ); document.write( "equation of a line: y=mx+b, m=slope, b=y-intercept
\n" ); document.write( "slope of given line=3
\n" ); document.write( "slope of perpendicular line=-1/3 (negative reciprocal)
\n" ); document.write( "equation:
\n" ); document.write( "y=-x/3+b
\n" ); document.write( "solve for b using coordinates of given point (6,-7)
\n" ); document.write( "-7=-6/3+b
\n" ); document.write( "-7=-2+b
\n" ); document.write( "b=-5
\n" ); document.write( "Equation of perpendicular line:
\n" ); document.write( "y=-x/3-5
\n" ); document.write( "slope of perpendicular line= -1/3
\n" ); document.write( "y-intercept of perpendicular line=-5 \n" ); document.write( "
