Answer:
How to Graph a Linear Inequality
First, graph the "equals" line, then shade in the correct area.
There are three steps:
1.) Rearrange the equation so "y" is on the left and everything else on the right.
2.) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
4.) Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

graph B shows the correct business equation.
we can represent it as
y = 5 + 2x
as x = 1 , y = 5+2×1=5+2=7
and so on.
A reasonable function is W = 7F + 5000
Where W is the weight of the plane and F is the number of gallons of fuel.
The domain is the set of possible values for F. That is from 0 (empty tank) to 400 (full tank).
So the domain is F = [0,400], or what is equivalente 0 ≤ F ≤ 400.
The range is the set of values of W.
The minimum value of W is when F = 0 => W = 7(0) + 5000 = 5,000.
The maximum value of W is when F = 400 => W = 7(400) + 5000 = 7,800
So the range is W = [5,000 ; 7,800], pr 5000 ≤ W ≤ 7,800.
