find the equation of the line perpendicular to y=-7/5x+100, passing through the points (-14,-52)\r
\n" ); document.write( "\n" ); document.write( "this line has slope m of -7/5
\n" ); document.write( "the perpendicular line needs to be -1/m and the product of the slopes needs to be -1
\n" ); document.write( "-1/m = -1/(-7/5) = 5/7 which is the slope of the perpendicular line
\n" ); document.write( "and -7/5 * 5/7 = -1\r
\n" ); document.write( "\n" ); document.write( "now need to solve for new b (y-intercept or vertical-intercept or point (0,b))
\n" ); document.write( "5/7 * -14 + b = -52
\n" ); document.write( "-70/7 + b = -52
\n" ); document.write( "-10 + b = -52
\n" ); document.write( "b = -42\r
\n" ); document.write( "\n" ); document.write( "equation of line is y = 5/7 * x - 42
\n" ); document.write( "
\n" ); document.write( "
