Can anyone answer this for me? Desperate right now.

unshaded area is 8 times bigger than shaded region

area of semi circle =2πcm²

area of circle =16πcm²

now,

let the shaded region be x times bigger

again

16πcm²=2πcm²*x

x=16πcm²/2πcm²

x=8

Step-by-step explanation:

(-2,-1), (2,1), (4,2)

Step-by-step explanation:

This is how I did it: (took me like a minute)

Draw a graph or get graph paper. You could also probably find a graph online that you can write on.  (remember to label)

Now mark two points of the line. So for this question you could use (0,0) and (2,1).

Now draw a line connecting both points.

Finally you can check whether the points are on the line or are not.

Hope this helps!
