Write an equation in standard form for the line described. through (7,9), perpendicular to 4x+y=7 \n" ); document.write( "----------------- \n" ); document.write( "The slope of the given line is -4 \n" ); document.write( "---- \n" ); document.write( "Any line that is perpendicular must have a slope of 1/4 \n" ); document.write( "---- \n" ); document.write( "Find equation of line with slope = 1/4 where y = 9 when x = 7. \n" ); document.write( "-------------------------- \n" ); document.write( "Form: y = mx + b \n" ); document.write( "Solve for \"b\": \n" ); document.write( "9 = (1/4)7 + b \n" ); document.write( "36/4 = 7/4 + b \n" ); document.write( "b = 29/4 \n" ); document.write( "============ \n" ); document.write( "y = (1/4)x + (29/4) \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============ \n" ); document.write( " |
