Answer:
D) 4x + 5y = -30 = -4/5
Step-by-step explanation:
A) 5x + 4y = 28 slope = -5/4
b) 4x-5y = -25 slope = 4/5
c) 4y - 5x = -12 slope = 5/4
d) 4x + 5y = -30 slope = -4/5
The unit rate is 5.
Here's why:
17 is a multiple of 85. To find the unit rate of eggs for 1 hen, you divide 85 divided by 17 which equals 5. So, for every 1 hen there are 5 eggs layed.

Answer:
(- 2, 3)
Step-by-step explanation:
The solution of the graphed system is the point of intersection of the 2 lines.
This occurs in the second quadrant where the x- coordinate is negative and the y- coordinate positive.
A reasonable estimate is therefore (- 2, 3)
