Write the equation of a line which has a slope of -1 and passes through the point (-2, -3).
\n" ); document.write( ":
\n" ); document.write( "Use the point/slope form, y - y1 = m(x - x1), where
\n" ); document.write( "m = -1
\n" ); document.write( "x1 = -2
\n" ); document.write( "y1 = -3
\n" ); document.write( ":
\n" ); document.write( "y - (-3) = -1(m - (-2))
\n" ); document.write( "minus a minus is plus
\n" ); document.write( "y + 3 = -1(x + 2)
\n" ); document.write( "distribute the -1
\n" ); document.write( "y + 3 = -1x - 2
\n" ); document.write( "subtract 3 from both sides
\n" ); document.write( "y = -x - 2 - 3
\n" ); document.write( "y = -x - 5 is the equation of a line with a slope of -1, passing thru -2,-3
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You can confirm this, replace x with -2 and find y
\n" ); document.write( "y = -(-2) - 5
\n" ); document.write( "y = 2 - 5
\n" ); document.write( "y = -3 \n" ); document.write( "
\n" );
