the given data is not linear, which you can verify as follows:
11 7.5
13.75 6
15 5.5
16.5 5
27.5 3

as you can see, the given data points do not fit the line perfectly, but you can use the line as a linear model of the given data, and use the linear model to estimate y for x=33 as follows:
---
linear model:
b = y-intercept = 9.54191291
m = slope = -0.247278383
---
slope-intercept form of linear model:
y = -0.247278383x + 9.54191291
---
y(33) = -0.247278383*33 + 9.54191291
y(33) = 1.381726271000002
