Hey! I can explain exactly how to do this. First off, we need to find slope to do slope intercept form, y = mx+b. To do this, we need two points, and use the formula y2-y1/x2-x1. Because I can't see the points clearly, I can give you an example. If we had (3,5) and (5,6), we would have 6-5/5-3, getting us 1/2 as our slope. Next, we need the y-intercept, or b. The way we find it is we see at which point does the like cross the y axis, the one that goes up and down. This point will always be (0, and then the y value) as there is no x value. Make sure to do this for all of these, and always write it in slope intercept. Message me if you need any more help! I'm here if you need me.

Add all the numbers together:
5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10= 136

divide the total with the total amount of numbers

136/17 = 8

Now add all the numbers again WITH the one

5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10 + 1= 137

Divide the total amount with the amount of numbers there are

137/18 = 7.61

7.61 < 8

The mean book rating will decrease by 0.39

hope this helps
