Parallel lines have the same slope,
\n" ); document.write( "because slope is the change in y for an x increase of 1,
\n" ); document.write( "and that is the tangent of the angle the line makes with the positive x axis.
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\"y=x%2B5\" is the equation of a line in \"highlight%28slope-intercept%29\" form.
\n" ); document.write( "That is the unique and very useful form that starts with \"y=\".
\n" ); document.write( "The number added at the end (5 in this case) is the intercept,
\n" ); document.write( "the y value for x=0, and therefore the y- coordinate of the point where the line \"intercepts\" the y-axis.
\n" ); document.write( "The number multiplying the x (an invisible 1 in this case) is the slope.
\n" ); document.write( "You can see that for x=0, y=5, but if you increase x by one,
\n" ); document.write( "for x=1, y=1+5 has increased by 1.
\n" ); document.write( "
\n" ); document.write( "The line parallel to \"y=x%2B5\" will have \"highlight%28slope=1%29\" and an intercept, \"b\" to be determined.
\n" ); document.write( "Its equation will be \"y=x%2Bb\"
\n" ); document.write( "We know that for that line the
\n" ); document.write( "point with \"x=2\" has \"y=3\" so substituting into \"y=x%2Bb\" we get
\n" ); document.write( "\"3=2%2Bb\" --> \"3-2=b\" --> \"highlight%28b=1%29\"
\n" ); document.write( "and the equation is \"highlight%28y=x%2B1%29\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
