Answer:
y=-3x+b
Step-by-step explanation:
To find whether or not an equation is parallel it has to have the same slope. To find this, you start by subtracting 9x from both sides, leaving you with 3y=-9x-22. Then you divide both sides by 3, leaving y=-3x-. With this equation you can see that the slope is -3. The answer will be any equation with -3x.

Answer:
Step-by-step explanation:
First we find out the area of circle, and then subtract the area of triangle from it to find the area of the shaded region
<u>Area of Circle</u>
Here, r=radius
area of circle= π×r²
= π × 5² (radius=half of diameter)
= 25π
= 78.54cm²
<u>Area of Triangle</u>
Here, b=base, h=height
area of triangle = ×b×h
= ×8×6
= 24cm²
Area of shaded region= area of circle - area of triangle
= 78.54 - 24
= 54.54
≈ 54.5cm² [Ans]
