Question

Which system below has no solution?

Answer 1

Answer:

None of the above.

If that isn't a choice, make sure you have written the equations correctly in your question. This is what I'm seeing:

y = 4x and y = 2x - 3

y = -4x and y = 2x - 3

y = -4x and y = 2x + 3

y = -4-x and y = 2x - 3

Step-by-step explanation:

We are looking for a system that has the same slope and a different y-intercept (the lines will be parallel in this case and never cross)

None of your pairs have the same same slope.

The first pair have slopes of 4 and 2 respectively.

The second pair have slopes of -4 and 2 respectively.

The third pair have slopes of -4 and 2 respectively.

The fourth pair have slopes of -1 and 2 respectively.

So all of these pairs will have one solution.
