A vendor has learned that, by pricing hot dogs at $1.00, sales will reach 142 hot dogs per dat. Raising the price to $2.00 will cause the sales to fall to 90 hot dogs per day. Let Y be the number of hot dogs the vedor sells at X dollars each. Write a linear equation that models the number of hot dogs sold per day when the price is X dollars each.

\n" ); document.write( "You have 2 points relating # of dogs(y) and price(x)::
\n" ); document.write( "Points: (1,142) and (2,90)
\n" ); document.write( "-----
\n" ); document.write( "slope = (142-90)/(1-2) = 52/(-1) = -52
\n" ); document.write( "--------
\n" ); document.write( "Form: y = mx + b

\n" ); document.write( "90 = -52*2 + b
\n" ); document.write( "b = 194
