Answer:
D
Step-by-step explanation:
If you are told that the slope is 2 that means that the equation cannot be A.
The slope is the number in front of the x. So far what you know is that
y = 2x + b
b is found from the given point.
- 7 = 2*(-8) + b Expand the right side
- 7 = - 16 + b Add 16 to both sides
- 7+16 = -16 + 16 + b
- 23 = b
answer y = 2x + 23
The answer is D
Answer: 60 Guppies.
Step-by-step explanation: If Ben has 3 times as much guppies as goldfish then it is 3 x 20 which = 60.

Answer:
x=-17, y=5. (-17, 5).
Step-by-step explanation:
-2x-5y=9
3x+11y=4
---------------
3(-2x-5y)=3(9)
2(3x+11y)=2(4)
---------------------
-6x-15y=27
6x+22y=8
-----------------
7y=35
y=35/7
y=5
3x+11(5)=4
3x+55=4
3x=4-55
3x=-51
x=-51/3
x=-17
