A number line going from 0 to 10. An open circle is at 7. Everything to the left of the circle is shaded.

Step-by-step explanation:

We have the following inequality:

-1.1x + 6.4 > - 1.3

to solve it, we need to isolate x, as follows:

-1.1x > - 1.3 - 6.4

-1.1x > - 7.7

x < - 7.7/-1.1 (notice that while dividing with a negative number, the sign changes)

x < 7
