Question

Which is a solution of the equation? 2x - y = 0 (1,2) (3) (3,-1) (2,-4)

Answer 1

Answer:

1,2

Step-by-step explanation:

all you have to do is plug in the values for their respective variables and solve accordingly. we have to try all answer choices to make sure we have the right one. we first plug 1,2 into the equation which gives us 2(1)-2=0. then we multiply 2 and 1, which is 2, so now we have 2-2=0. we know that 2-2=0, so we now know that the first answer choice is the correct one.
