Based on the data shown below, a statistician calculates a linear model $\displaystyle {y}={0.34}{x}+{5.33}$.

x	y
4	8.7
5	6.1
6	5.8
7	6.7
8	8.4
9	10.1
10	7
11	10

Use the model to estimate the y-value when $\displaystyle {x}={6}$
y =
Use the model to estimate the y-value when $\displaystyle {x}={4}$
y =
