The answer is 1 bc the solution is (1,-3)
Hope this helps! I'm sorry for worse handwriting.
x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
$4.20 / 36 = $0.11667 per potato<span>

Midpoint formula = (-9 + 6) / 2 = -3/2
