I do not understand your question very well but I think that the state of the glass of the water would be liquid and solid at the same time since the water would not freeze 100% and would be with small pieces of solid and some parts liquid, in terms of temperature, I think that at 5 minutes it would be 5 ° C and at 10 it would be 3-4 ° C the longer it is in the freezer the less its temperature will be
Y - y1 = m(x - x1) slope(m) = -6 (-2,-3)...x1 = -2 and y1 = -3 now sub and pay close attention to ur signs y - (-3) = -6(x - (-2)....we're not done yet... y + 3 = -6(x + 2) <===
