Question 145273: A. What are the coordinates of tree A(-20,20); plant B (-20,-4); plant C (-10,-14); plant D (12,12); plant E (8, -8); and plant F (18,-12?
B. The water line is given by the equation y= -2/3x - 12. 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 (-4,-10)?
C. What is the slope and y- intercept of the line in part b? How do you know?
D. Suppose you want to add a sprinkler system, and the location of one section of the sprinkler line can be described by the equation y= - 1/2x - 4.
Complete the table for this equation.
x___-1___(x,y)
-2__y___(x,y)
x___-4___(x,y)
2___y____(x,y)
8___y____(x,y)
E. What objects might be in the way as you lay the pipe for the sprinkler?

Comment: I don't understand what your question is?

B. The water line is given by the equation y= -2/3x - 12. 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 (-4,-10)?
Substitute x=-4 and y=-10 to determine if the point is on the line:
-10 = (-2/3)(-4) -12
-10 = (8/3)-12
Wrong
The point is not on the line.
You could place it at that point.
-----------------------------------
C. What is the slope and y- intercept of the line in part b? How do you know?
y= -2/3x - 12
slope = (-2/3) because y decreases 2/3 as x increases by 1.
y-intercept = -12 because y = -12 when x = 0.
-----------------------------------
D. Suppose you want to add a sprinkler system, and the location of one section of the sprinkler line can be described by the equation y= - 1/2x - 4.
Complete the table for this equation.
x___-1___(x,y) = (-6,-1)
-2__y___(x,y) = (-2,-3)
x___-4___(x,y) = (0,-4)
2___y____(x,y) = (2,-5)
8___y____(x,y) = (8,-8)
------------------------------------
E. What objects might be in the way as you lay the pipe for the sprinkler?
I wouldn't know.
