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.
