Algebra.Com's Answer #816291 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The equation of line passing through origin and perpendicular to line: \n" ); document.write( "2x + y - 5 = 0 is ____? \n" ); document.write( "Change to the slope/intercept form \n" ); document.write( "y = -2x + 5 \n" ); document.write( "the slope is -2, find the slope of a perpendicular line, s1*s2 = -1 \n" ); document.write( "-2*s2 = - 1 \n" ); document.write( "s2 = +.5 \n" ); document.write( "The line goes thru origin, therefore intercept is 0 \n" ); document.write( "The equation, then: y = .5x \n" ); document.write( "put it back in the original form, mult eq by 2 and rearrange \n" ); document.write( "x - 2y = 0 \n" ); document.write( ": \n" ); document.write( "Answer is E \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
