Use the point slope equation: y - y1 = m(x - x1)
(-1, -3); m = 4
Plug these numbers in.
y - (-3) = 4(x - -1)
y + 3 = 4x + 4
y = 4x + 1
There is a 1/3 chance. Add up the shaded parts for a total of 120 degrees. 120/360 is 1/3
A = 28.26 units^2
Step-by-step explanation:
The formula for the area of a circle is:
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
We can just plug in the numbers and solve.
![A=3.14*3*3](https://tex.z-dn.net/?f=A%3D3.14%2A3%2A3)
![A=](https://tex.z-dn.net/?f=A%3D)
