A= base(one) + base(two)/2 * height
A= 9+14/2 * 11
A= 23/2 * 11
A= 11.5 * 11
A = 126.5 inches
The solution of the system of equation is (-2 ,2).
<h3>What is a System of Equation ?</h3>
A system of equation is defined as the equation that have a common solution.
The system of equation is
x+y = 0
y = 2x+6
2x-y = -6
3x = -6
x = -2
y = 2
The graph of both the equations are plotted and the common point is the solution of the equations.
The solution of the system of equation is (-2 ,2).

Hi There!
----------------------------------------------
Part A:
Slope Intercept Form: y = mx + b
m = slope (slope =
)
b = y intercept

b = 3
Answer: y = -1/2x + 3
----------------------------------------------
Part B:
Just substitue f(x) for y.
Function Notation = f(x) -1/2 + 3
----------------------------------------------
Part C:
This function given looks almost the same but the slope is different while the one stated in the question has a slope of +2 and the equation given at the start with the slope being -1/2.
