Assuming constant temperature within the system.
FYI if the pressure matched the volume across the board, the shape of the curve would be a straight line from the origin (lower left) at a 45 degree angle to the upper right. So of course that's not what it shows, but I thought I'd mention that so you know what to look for if that ever happens on a graph, which sometimes it might, though it wouldn't happen with pressure and volume.

ETA- it asked if the pressure is 8 what is the volume? But to me it looks like the volume matches the pressure across the board so the volume would be an 8 as well,

Yes, but I still do not understand the way to read it, we need an explanatin as to what we are reading wrong here.
As it reads to me, it appears that the answer would be 2 but that is not correct, I don't really want the answer so much as the means to arrive at it. I don't seem to be able to see what my mistake is.
I swear it looks to me like, if the pressure is 8 then the volume would be a 2, but am not sure myself, as 8 am unfamiliar with this kind of graph.

Thank you sir! Duh!!! Lol I feel so dumb now, I should have seen that for what it is, I don't know what I was thinking. Stars for you guyhs thanks!
Not exactly. Inverse proportionality is linear as the first graph in this link shows for the equation y=-2x+3:

The form of inverse proportionality is a straight line sloping down and to the right.
The curve in the OP is not inversely proportional (because for one thing, it's not a straight line), it's called a power function. See the 4th graph down at that same link for some examples and comments about the math of a power function.

Thanks, I stand corrected, I guess I needed a stronger cup of coffee, because I knew that, sorry.
