Answer:
The point slope formula is
(y−y1)=m(x−x1)
Where m = the slope calculated as y2−y1x2−x1
(x1,y1)(x2,y2)
(-4 , 1) (-2 , 3)
Solve for the slope
m = 3−1−2−(−3) = 21 = m = 2
(y−3)=2(x−(−2)) Plug in known values.
y−3=2(x+2) Simplify signs
y−3=2x+4 Use Distributive property
y=−2x+4+3 isolate the y variable
answer (y = −5x+7 ) Simplify
Cosine is
.
Apply the equation:

B is the adjacent side so
cosine is:
Cos(t) = 5/2

Answer:
40 points
Step-by-step explanation:
The radius is half the diameter, so the formula would be r=d divided by 2
