Drag each system of equations to the correct location on the graph. Match each system of equations to its point of intersection. y = -x + 2 y = 2x − 3 y = -x + 2 y = 2x − 1 y = -x + 2 y = 5x + 2 y = 5x + 2 y = -x − 1 y = -x − 1 y = 2x − 3

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Which statement accurately explains whether a reflection over the y axis and a 270° counterclockwise rotation would map figure acb onto itself?
