Find the slope of any line perpendicular to the line through points (0, 5) and (-3, -4).\r \n" ); document.write( "\n" ); document.write( "1- The formula for slope is y2-y1/x2-x1. \n" ); document.write( " Let y2=-4, y1=5, x2=-3, x1=0 \n" ); document.write( " -4-5/-3-0 \n" ); document.write( " -9/-3 \n" ); document.write( " 3 \n" ); document.write( "2- The slope of the line is 3. The slopes of perpendicular lines are negative reciprocals of each other. The slope of any line perpendicular to this line would be -1/3.\r \n" ); document.write( "\n" ); document.write( "3- Why is the slope of the perpendicular line -1/3? The reciprocal of 3 is 1/3. To find the negative reciprocal, change the sign. \n" ); document.write( " \n" ); document.write( " |
