Step-by-step explanation:
The boundary lines are drawn by considering the relation as an equation.
The first "equation" describes a line with slope -8/3 through the y-intercept point (0, 6). Another point on that line would be 8 units down and 3 units right of (0, 6), at (3, -2). Both inequalities include the "or equal to" case, so both boundary lines are solid lines.
Since we have y ≥ ( ), the shading is above the line.

The second "equation" describes a line with a slope of 5/3 through the y-intercept point (0, -7). Another point would be 5 units up and 3 units right of (0, -7), at (3, -2). Since we have y ≤ ( ), the shading is below the line.
That is, the solution region is in the right-hand quadrant of the X where the lines cross. It includes the lines themselves.
To calculate percent change.... First work out
the difference (increase) between the two numbers you are comparing. Then
divide the increase by the original number and multiply the answer by 100.
(if your answer is a negative number then that is a percentage decrease.)
The formula for percent change:
((y2 - y1) / y1)*100 = your percentage change.
Problem work:
y1 =16
y2 = 44.2
( 44.2-16/16) x 100
(1.7625) x 100
So the percent increase (percent change) will be 176.25%
