Need help with this problem please.
\n" ); document.write( "Find the equation of the line that contains the point (-2,-1) and has slope -1/2.
\n" ); document.write( ":
\n" ); document.write( "You seem to have the right idea, however, I's going to give you the whole procedure and you can decide where you went wrong.
\n" ); document.write( ":
\n" ); document.write( "We're going to use the point/slope form: y - y1 = m(x - x1)
\n" ); document.write( ";
\n" ); document.write( "In your problem x1 = -2; y1 = -1; m = -1/2
\n" ); document.write( ":
\n" ); document.write( "So we have:
\n" ); document.write( "y - (-1) = \"-1%2F2\"(x - (-2))
\n" ); document.write( ":
\n" ); document.write( "Remember minus a minus is a plus:
\n" ); document.write( "y + 1 = \"-1%2F2\"(x + 2)
\n" ); document.write( ":
\n" ); document.write( "Multiply what's inside the bracket by -1/2
\n" ); document.write( "y + 1 = \"-1%2F2\"x - 1
\n" ); document.write( ":
\n" ); document.write( "Subtract 1 from both sides:
\n" ); document.write( "y = \"-1%2F2\"x - 1 - 1
\n" ); document.write( ":
\n" ); document.write( "y = \"-1%2F2\"x - 2
\n" ); document.write( "
\n" );
