Algebra.Com's Answer #352317 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! 1)Write the slope-intercept equation for the line that passes thru (-12,10) and is perpendicular to 4x+6y=3 \n" ); document.write( "---------------------- \n" ); document.write( "Find the slope, m, of 4x+6y = 3 \n" ); document.write( "To do that solve for y \n" ); document.write( "y = (-2/3)x + 1/2 \n" ); document.write( "m = the coeff of x, = -2/3 \n" ); document.write( "---------- \n" ); document.write( "The slope of lines perpendicular is the negative inverse, = 3/2 \n" ); document.write( "Use y = mx + b and the point to find b \n" ); document.write( "10 = (3/2)*-12 + b \n" ); document.write( "b = 28 \n" ); document.write( "--------- \n" ); document.write( "Eqn is y = (3/2)x + 28 \n" ); document.write( "---------------------- \n" ); document.write( "Do #2 the same way. \n" ); document.write( "2)Write the slope-intercept equation for the line that passes thru (-3,-15) and is perpendicular to -6x+8y=3 \n" ); document.write( " |
