Question 241154: . The following graph shows the growth of the median home value in a particular region of the United States starting in 1996. The graphs starts in 1996 and shows the trend through the year 2000; therefore x = 0 represents the year 1996 and x = 4 is 2000.
X – axis (horizontal) = years starting from 0 = 1996 and increasing by 1.0 years
Y – axis (vertical) = price in $ amounts

Question 271727: The backyard can be mapped onto a Cartesian coordinate (x,y) graph. Using the various items described in the yard below, answer the following questions.
a) A water line is given by the equation.
y=-0.6x+3.2
Suppose you want to put a pink flamingo lawn ornament in your backyard, but you want to avoid placing it directly over the water line, in case you need to excavate the line for repairs in the future. Could you place it at the point (-0.375,6) ? Demonstrate how you arrived at your answer with the detail calculations.
b)What is the slope and y-intercept of the line in part a? How do you know?
