Algebra.Com's Answer #97 by terrtwo(10)![]() ![]() ![]() You can put this solution on YOUR website! By definition to find a perpendicular line to a given line, the slope of the perpendicular line will be the negative reciprocal. \r \n" ); document.write( "\n" ); document.write( "For the equation of the line y = 4x - 3, the slope(the m in y = mx +b) is equal to 4, m = 4\r \n" ); document.write( "\n" ); document.write( "The slope for the prependicular line is therefore -1 * ( 1 / m) --> (-1 * 1)/ 4,\r \n" ); document.write( "\n" ); document.write( "--> -1/4 \n" ); document.write( " |
