What is the equation of a line with a slope of -5 and containing the point (2,4): \n" ); document.write( ": \n" ); document.write( "use the point/slope formula: (y - y1) = m(x - x1) \n" ); document.write( ": \n" ); document.write( "In your problem m = -5, x1=2; y1=4, so substitute and you have: \n" ); document.write( "y - 4 = -5(x - 2) \n" ); document.write( ": \n" ); document.write( "y - 4 = -5x -5(-2);multiplied what's inside the brackets, \n" ); document.write( ": \n" ); document.write( "y - 4 = -5x + 10; minus * minus = + \n" ); document.write( ": \n" ); document.write( "y = -5x +10 + 4; add 4 to both sides \n" ); document.write( ": \n" ); document.write( "y = -5x + 14, is the equation \n" ); document.write( " |
