Algebra.Com's Answer #360543 by Alan3354(69443) You can put this solution on YOUR website! Write the slope-intercept equation for the line that passes through (-2,3) and is perpendicular to 2x – 9y = -12 \n" ); document.write( "----------- \n" ); document.write( "Find the slope of the line. \n" ); document.write( "Solve for y: \n" ); document.write( "2x – 9y = -12 \n" ); document.write( "9y = 2x + 12 \n" ); document.write( "y = (2/9)x + 4/3 \n" ); document.write( "----- \n" ); document.write( "The slope of the line is 2/9 \n" ); document.write( "The slope of lines perpendicular is the negative inverse, = -9/2 \n" ); document.write( "----- \n" ); document.write( "Use y = mx + b and the point to find b, the y-intercept \n" ); document.write( "3 = (-9/2)*(-2) + b \n" ); document.write( "b = -6 \n" ); document.write( "----- \n" ); document.write( "--> y = (-9/2)x - 6 \n" ); document.write( " \n" ); document.write( " |
