Answer:
A
Step-by-step explanation:
2x is the parent function and -6 is the y intercept
The y intercept is when x = 0.
In that case y = - 6 just from reading the graph.
So far what you know is
y = mx - 6
So B and C are both incorrect.
Now you need the slope. That can be calculated from the x and y intercept.
m = (0 - -6)/(3 - 0)
m = 6 / 3
m = 2
y = 2x - 6
The answer is A
X is increasing by 2 and Y is decreasing by -3. : )
Area of the triangle = 6x3/2=18/2=9cm²
now find semicircle then add
area of the semicircle= πr²/2=π6²/2=36π/2=18π
now add and you get
Area of the region = (18π+9)cm²
