Think of an x-y plot where x is the years passed
\n" ); document.write( "and y is the salary
\n" ); document.write( "I can say when
\n" ); document.write( "\"+S+=+60+\" ( salary in thousands)
\n" ); document.write( "\"+t+=+0+\"
\n" ); document.write( "---------
\n" ); document.write( "when
\n" ); document.write( "\"+S+=+70.5+\"
\n" ); document.write( "\"+t+=+3+\"
\n" ); document.write( "---------
\n" ); document.write( "I can write the equation in point-slope form
\n" ); document.write( "\"+%28+S+-+60+%29+%2F+%28+t+-+0+%29+=+%2870.5+-+60+%29+%2F+%283+-+0+%29+\"
\n" ); document.write( "\"+%28+S+-+60+%29+%2F+t+=+10.5+%2F+3+\"
\n" ); document.write( "multiply both sides by \"+3t+\"
\n" ); document.write( "\"+3%2A%28+S+-+60+%29+=+10.5t+\"
\n" ); document.write( "\"+3S+-+180+=+10.5t+\"
\n" ); document.write( "\"+3S+=+10.5t+%2B+180+\"
\n" ); document.write( "\"+S+=+3.5t+%2B+60+\"
\n" ); document.write( "check:
\n" ); document.write( "When \"+t=0+\", he makes $60 thousand -OK
\n" ); document.write( "When \"+t+=+3+\", he makes \"+3.5%2A3+%2B+60+=+70.5+\" thousand -OK
\n" ); document.write( "--------------
\n" ); document.write( "The slope is how fast his salary is increasing
\n" ); document.write( "The S-intercept is his starting salary
\n" ); document.write( "--------------
\n" ); document.write( "After 12 years,
\n" ); document.write( "\"+S+=+3.5%2A12+%2B+60+\"
\n" ); document.write( "\"+S+=+42+%2B+60+\"
\n" ); document.write( "\"+S+=+102+\"
\n" ); document.write( "He will make $102,000 after 12 years
\n" ); document.write( "
\n" );
