I am really confused...can someone help me with this? I am supposed to graph solution of given system of linear inequality:
y is greater than 4x3
y is less than or equal to x+2

Consider the "equation" of the corresponding function, I will use yours as an example
y = 4x3
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 < 4x3 , 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)
