Algebra.Com's Answer #300213 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! First put the equation 2x-4y=9 in standard form: \n" ); document.write( "y = 1/2x - 9/4 \n" ); document.write( "The slope of the perpendicular line is the negative reciprocal of 1/2 = -2 (you were correct!) \n" ); document.write( "The point-slope form for a line is: \n" ); document.write( "y - y1 = m(x - x1) \n" ); document.write( "Using the point (x1,y1) = (-1/4,1/2) we get: \n" ); document.write( "y - 1/2 = -2(x - -1/4) \n" ); document.write( "This gives y = -2x \n" ); document.write( "So, the y-intercept is 0 (you were correct!) \n" ); document.write( "The lines are shown below: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
