points ( 60, $1635) (120, $1770_
\n" ); document.write( "I got a slope of 2.25
\n" ); document.write( "That is correct:
\n" ); document.write( "---------------------
\n" ); document.write( "My intercept is 1,500.
\n" ); document.write( "Substitute into y = mx+b to solve for \"b\"
\n" ); document.write( "1635 = 2.25*60 + b
\n" ); document.write( "b = 1500
\n" ); document.write( "You are correct:
\n" ); document.write( "---------------------
\n" ); document.write( " Not sure if this is right. Let x represent packages and y cost. What is the cost to send 200? What would my equation look like?
\n" ); document.write( "EQUATION:
\n" ); document.write( "y = 2.25x + 1500
\n" ); document.write( "To send 200 you get y = 2.25*200 + 1500
\n" ); document.write( "y = 450 +1500
\n" ); document.write( "y = 1950
