    Inequalities

    This seems straightforward. Is it really as simple as drawing a line from -2 to 3 horizontally parallel to the existing one on the diagram?

    "the following integers" are missing. a lot of integers are like children, you have to keep close watch on them because they tend to wander and get lost

    lucky you. usually the integers i work with are naughty. i'd draw the inequality -2 \leq x \leq 3

    you could actually draw any inequality ranging from -4 \leq x \leq 6 but encompassing the region -2 \leq x \leq 3

    do you know how to do that?

    Well, I would draw a line from the point 3 to just after -2.

    that's fine. but note if you draw the line from point 3, you'd have to shade the circle, if you're going to draw it extending past -2, then you don't have to shade that one

    Shade the circle? I don't understand. Do you mean that black spot?

    yes the black spot, it was actually a circle that was shaded in. we shade the circle if we have \geq or \leq, we leave it unshaded if we have > or <
