The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!
Answer:

Answer:
linear
Step-by-step explanation:
The graph would be linear since it's .05 every minute, which would mean that every minute it would cost .05 --> adding up minutes. The flat fee at the beginning is trying to trick you up, don't get fooled ;)
Answer:
No solutions.
Step-by-step explanation:
-2x - y = 1
-4x - 2y = -1 Multiply the first equation By -2:
4x + 2y = -2 Adding:
0 = -3
which is absurd so there are no solutions.
Answer:
No, (-1,4) is not a solution.
Step-by-step explanation:
This is actually a simple problem...don't overcomplicate it!
All you need to do is plug the values into the equation and solve!
y < 2x + 5
4 < 2(-1) + 5
4 < 3
