Вершина первой параболы:
Xв = - b/2a = - -6/2*1 = 3
Yв = 3^2 - 6*3 + 7 = 9 - 18 + 7 = -2
A(3; -2).
Вершина второй параболы:
Xв = -b/2a = - -4/2*(-1) = -2
Yв = - (-2)^2 - 4*(-2) - 5 = -4 + 8 - 5 = -1
B(-2; -1).
Составим уравнение прямой, проходящей через эти точки:
(x - x1)/(x2 - x1) = (y - y1)/(y2 - y1)
(x - 3)/(-2 - 3) = (y - (-2))/(-1 - (-2))
(x - 3)/-5 = (y + 2)/1
y = - (x - 3)/5 - 2 = (-x + 3 - 10)/5 = (-x - 7)/5 = - x/5 - 7/5
