The solution values for x is the x-axis in the shaded region all the way towards but not equal to negative infinity.

Determine the x-intercept for $y=-7x+4$ : and you then substitute in:

$-oo < x < x_("intercept")$

Notice that you can not include the x-intercept as $y$ is less than...
That is why the line is dotted

If we had $y<= than$ then we could include the x-intercept.
