**Reiny**, Saturday, November 20, 2010 at 9:32amConsider the "equation" of the corresponding function, I will use yours as an example

y = 4x-3

Since it is a straight line, all you need are two points

since you had

y > 4x - 3, draw a dotted line to show that the points are excluded.

Shade in the region**above**that line

If the relation had been

y < 4x-3 , you would shade in the region**below**the line

If the relation had been ≥ or ≤ , you would make the boundary line solid, to show the points on the line would be included.

my explanation applies to all inequations of the form

y > f(x), y < f(x), y ≥ f(x), or y ≤ f(x)
