Point a (2,1) partitions QR in the ratio of 3 to 2. The coordinates of point QR (-4,-5)). What are the coordinates of point R

How do you solving the solution of each system using elimination?

Give me the equations of two lines that have the same slope but are not parallel.

1- 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.2- 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 the first question?
