    -8-2 ≥ -5x > -38-2 =>-10 ≥ -5x > -40 =>2 ≥ x > 8

    SO THE WHITE DOTS MEAN THAT IT IS A OPEN INTERVAL?

    well so inequalities are plotted by intervals?

    I am not quite sure, what your question is. But I can at least say, that inequalities can be equivalently expressed as intervals, e.g The inequality a≥x≥b is equivalent to [b,a] The inequality a≥x>b is equivalent to (b,a] and so on...

    -8 \[\ge\] -5x + 2 > - 38 = -8 \[\ge\] -5x divide trough by five. so -5x/5 = -8/5 = x \[\le\] 1.4 +2 > -38 = +2/2 > -38/2 = 1 > - 19 = x \[\le\] 1.4 + 1 > -19
