Y = 10x
I know this is the answer because for each plot that is on the graph it goes up 10 points. That means that the slope would be 10x. Two of the answers both have a number after the X meaning that there would have to be a Y-Intercept but the graph does not show this so that rules out Options 1 and 2. Option 4 doesn't apply because it is not the verticle scale and also for every 10 units that go up the time one moves up 1 unit ruling out Option 4. That leaves the only answer to be Option 3: Y = 10x.
Hope this helps and have a nice day.
