Find an equation of the line containing the given pair of points \n" ); document.write( "(-3,-4) and (-8,-1) \n" ); document.write( "--------------- \n" ); document.write( "slope = (-1--4)/(-8--3) = 3/-5 = -3/5 \n" ); document.write( "------------------ \n" ); document.write( "Form: y = mx + b \n" ); document.write( "--- \n" ); document.write( "Substitute for y,x,m and solve for \"b\": \n" ); document.write( "--- \n" ); document.write( "-1 = (-3/5)*-8 + b \n" ); document.write( "-1 = (24/5) + b \n" ); document.write( "-(5/5) = (24/5) + b \n" ); document.write( "b = -(29/5) \n" ); document.write( "-------------------- \n" ); document.write( "Equation: \n" ); document.write( "y = (-3/5)x - (29/5) \n" ); document.write( "========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============= \n" ); document.write( " |
