Algebra.Com's Answer #429373 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Line a is perpendicular to line b. Line a has an equation y=-3x-4. What is the equation of line b if line b passes through the point (-3,4) \n" ); document.write( "---- \n" ); document.write( "The given line has slope = -3. \n" ); document.write( "--- \n" ); document.write( "Any perpendicular must have slope = 1/3 \n" ); document.write( "----- \n" ); document.write( "Your Equation ?? \n" ); document.write( "Form: y = mx + b \n" ); document.write( "---- \n" ); document.write( "slope = 1/3 and y = 4 when x = -3; solve for \"b\": \n" ); document.write( "4 = (1/3)(-3) + b \n" ); document.write( "--- \n" ); document.write( "4 = -1 + b \n" ); document.write( "b = 5 \n" ); document.write( "----- \n" ); document.write( "Equation: y = (1/3)x + 5 \n" ); document.write( "========================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
