document.write( "Question 1000601: a vendor has learned that, by pricing caramel apples at $1.50, sales will reach 94 caramel apples per day. raising the price to $2.50 will cause the sales to fall to 42 caramel apples per day. let y be the number of caramel apples the vendor sells at x dollars each. write a linear equation that models the number of caramel apples sold per day y when it comes to the price x dollars each \n" ); document.write( "

The description can help to form a simple data table for two linear points.

\r\n" );
document.write( "x           y\r\n" );
document.write( "1.5         94\r\n" );
document.write( "1.5+2.5     94-42\r\n" );
document.write( "

\n" ); document.write( "These are points, (1.5,94) and (3,52).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A neat way to setup the equation is to use both formula for slope and the linear equation in point-slope form using the second point:\r
