Find the point-slope equation of a line that has a slope of 3/4 and passes through the point(-6,-2). Then, solve for y. \n" ); document.write( "------------------------ \n" ); document.write( "Form: y = mx + b \n" ); document.write( "You are told that m=3/4 and that y = -2 when x = -6 \n" ); document.write( "So substitute those values to solve for \"b\": \n" ); document.write( "-2 = (3/4)(-6) + b \n" ); document.write( "Multiply thru by 4 to get: \n" ); document.write( "-8 = -18 + 4b \n" ); document.write( "4b = 10 \n" ); document.write( "b = 5/2\r \n" ); document.write( "\n" ); document.write( "================= \n" ); document.write( "Equation: \n" ); document.write( "y = (3/4)x + (5/2) \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stam H. \n" ); document.write( " |
