Q:

Which system below has no solution?y = 4x and y = 2x - 3y = -4x and y = 2x - 3y = -4x and y = 2x + 3y = -4-x and y = 2x - 3it is multiple choice

Accepted Solution

A:
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 - 3Step-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.
