The table shows the median home prices in Florida. What is the equation of a trend line that models a relationship between time
and home prices? Use the equation to predict the median home price in 2020.

Answer:
A) Price= 1617*Year - 3.116e+006; B) 150340$ By 2020
Step-by-step explanation:
We have a data set of 7 x, y pairs, this data set can be modelled as line, applying a linear regression calculator we found that the trend line can be modelled as Price= 1617*Year - 3.116e+006
Attached you will find the regression results where x is the year variable and Y is the price. If we now plug year=2020 in the equation we have:
Price=1617*2020-3.116e+006 = 150340$

Answer:
(-2, 3)
Step-by-step explanation:
A is translated from (5, 1) to A' at (6, -2).
That is, it moves <em>one unit to the right and three units down</em>.
B is also translated to B' one unit to the right and three units down to (-1, 0).
B must be <em>one unit to the left and three units above B'</em>.
Thus, the coordinates of B are (-2, 3).
The diagram below shows the translation of side AB of ∆ABC to its new location at A'B'.
