\n" ); document.write( "
\n" ); document.write( "Given points: (3,2) & (9,5)
\n" ); document.write( "We first find the Slope via Slope-Intercept Form, \"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"
\n" ); document.write( "Substituting,
\n" ); document.write( "\"m=%285-2%29%2F%289-3%29=3%2F6=1%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then thru point (3,2) via Slope-Intercept Form, y=mx+b:
\n" ); document.write( "\"2=%281%2F2%293%2Bb\"--->\"2=3%2F2%2Bb\"
\n" ); document.write( "\"b=2-3%2F2=%284-3%29%2F2=1%2F2\" Y-Intercept
\n" ); document.write( "Also, thru (9,5): (should be the same)
\n" ); document.write( "\"5=%281%2F2%299%2Bb\" --->\"5=9%2F2%2Bb\"
\n" ); document.write( "\"b=5-9%2F2=%2810-9%29%2F2=1%2F2\"
\n" ); document.write( "The Line Eqn ==> y=(1/2)x+(1/2), Answer
\n" ); document.write( "We see graph,
