This means that if b doubles, then a will become half as large. For the inverse of the ratio 2 to 1 ("doubles") is the ratio 1 to 2 ("half"). The terms are exchanged; the inverse of the ratio a : b is the ratio b : a.
When a varies inversely as b, we say that a is inversely proportional to b.

Answer:
(-1,4)
Step-by-step explanation:
First lets put the two equations into y=mx+b format by subtracting 2x and 4x to the right side of their equations.
y=-2x+2
y=-4x+0
Now you can put this into a system of equations, but you can also plug in the coordinates to see if both equations are equal. I will show system of equations solution.
-2x+2=-4x, solve this by adding -2x to the right side so that the 2 is by itself.
Now you have 2=-2x. Divide by -2 to get the x by itself, now you have x=-1. Plug this back into one of the equations, so y=-4x would be y=-4(-1), so y=4.
