Determine which system below will produce infinitely many solutions.
−6x + 3y = 18
4x − 3y = 6
2x + 4y = 24
6x + 12y = 36
3x − y = 14
−9x + 3y = −42
5x + 2y = 13
−x + 4y = −6

Best ResponseYou've already chosen the best response.2infinitely many solutions occur when one equation is a multiple of the other. Basically they produce they produce the same line in the coordinate plane.

Best ResponseYou've already chosen the best response.0Okay.. so what would I do to find the answer?

Best ResponseYou've already chosen the best response.2an example would be x + y = 6 2x  2y = 12  because the second equation = first multiplied by 2

Best ResponseYou've already chosen the best response.2see if you can find something similar in the 4 given options are the y , x terms and the number in one equation multiplied by the same value to get the other?

Best ResponseYou've already chosen the best response.2yw Hint  at first it looks like number 2 is the one because 2x* 3 = 6x and 4y * 3 = 12y but 24 *3 does not equal 36 so its not that one.

Best ResponseYou've already chosen the best response.2look at number 3 how do you go from 3x to 9x, and y to 3y and 14 to 42?

Best ResponseYou've already chosen the best response.2if you plotted them on a graph paper thay would be the same line. That is why there are infinite solutions  they are all along this infinitely long line!
