$a). : y = - 2 times ( - 3.5) + 8 = 15 \ b) : 5.5 = - 2x + 8 \ 2x = 8 - 5.5 \ 2x = 2.5 \ x = 2.5 div 2 \ x = 1.25 \ b = - 2 times ( - 1.5) + 8 = 3 + 8 = 11 : da : tochka : b : prohodit \ \ 18x - 4 = - 2x + 16 \18x + 2x = 16 + 4 \ 20x = 20 \ x = 1 \ y = 18 times 1 - 4 = 14 \ tochki : peresechenia : (1 : i : 4)$
