You can put this solution on YOUR website!
The point-slope formula is used when you are
\n" ); document.write( "given ether:
\n" ); document.write( "(1) a point and a slope
\n" ); document.write( "(2) 2 points
\n" ); document.write( "------------
\n" ); document.write( "Suppose you are given 2 points such as
\n" ); document.write( "( 3,5 ) and ( 1,9 )
\n" ); document.write( "You can plug these into the point-slope formula
\n" ); document.write( "to find the equation of the line passing through these points
\n" ); document.write( "\"+%28+y+-+5+%29+%2F+%28+x+-+3+%29+=+%28+9+-+5+%29+%2F+%28+1+-+3+%29+\"
\n" ); document.write( "( note that both sides are ( change in y ) / ( change in x )
\n" ); document.write( "\"+%28+y+-+5+%29+%2F+%28+x+-+3+%29+=+4%2F%28-2%29+\"
\n" ); document.write( "\"+%28+y+-+5+%29+%2F+%28+x+-+3+%29+=+-2+\"
\n" ); document.write( "Multiply both sides by \"+x+-+3+\"
\n" ); document.write( "\"+y+-+5+=+-2%2A%28+x+-+3+%29+\"
\n" ); document.write( "\"+y+-+5+=+-2x+%2B+6+\"
\n" ); document.write( "\"+y+=+-2x+%2B+11+\"
\n" ); document.write( "check answer:
\n" ); document.write( "Does it pass through ( 3,5 )?
\n" ); document.write( "\"+5+=+-2%2A3+%2B+11+\"
\n" ); document.write( "\"+5+=+-6+%2B+11+\"
\n" ); document.write( "\"+5+=+5+\"
\n" ); document.write( "OK You can check other point
\n" ); document.write( "
\n" );
