WRITE THE EQUATION FOR THE HORIZONTAL LINE THROUGH THE POINT (-3,5)\r

\n" ); document.write( "
\r\n" );
document.write( "Let's plot the point:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now let's draw the horizontal line through it:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now let's plot another arbitrary points on that line:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The arbitrary point on that line I chose is (2,5).\r\n" );
document.write( "\r\n" );
document.write( "Question:  What do those two points have in common?\r\n" );
document.write( "Answer:    They have the same y-coordinate, which is 5.\r\n" );
document.write( "\r\n" );
document.write( "Let's plot another point on that line:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The arbitrary point on that line I chose this time is (-8,5).\r\n" );
document.write( "\r\n" );
document.write( "Question:  What do those three points all have in common?\r\n" );
document.write( "Answer:    They all three have the same y-coordinate, which is 5.\r\n" );
document.write( "\r\n" );
document.write( "Do you see that no matter how many arbitrary points I pick on that line,\r\n" );
document.write( "every one of them will have the same y-coordinate 5?\r\n" );
document.write( "\r\n" );
document.write( "Since that is true for every point on that line, the equation of that line\r\n" );
document.write( "could be the sentence:\r\n" );
document.write( "\r\n" );
document.write( "  \"The y-coordinate of every point on that line equals 5\"\r\n" );
document.write( "\r\n" );
document.write( "But we just shorten it to simply\r\n" );
document.write( "\r\n" );
document.write( "           y = 5\r\n" );
document.write( "\r\n" );
document.write( "That's the equation of that horizontal line.\r\n" );
document.write( "\r\n" );
document.write( "Similarly every horizontal line has a very simple equation  \r\n" );
