Question 83046
First make a number line with a point at 7.

{{{number_line( 600, -10, 10,7)}}}


Now shade everything to the right of 7. Every point in this shaded region makes {{{x>7}}}. For instance, 10 is to the right of 7 (it is greater than 7) so it means {{{10>7}}} is true. However, since {{{7>7}}} is not true, you must not shade at 7. So this means there's an open circle at 7


Here's what it should look like. The blue region is the shaded region.
