Answer:

See Below

Step-by-step explanation:

Ok, line needs to be parallel. Therefore, it should have the same slope.

y = -2x + b

Plugin the points and solve for y-intercept

(-1,7)

7 = -2(-1) + b

7 = 2 + b

-2 -2

5 = b

Plug it all in

y = -2x +5

Calculate the length of a minor arc OP in terms of π

Tanzania [10]

Answer:

arc length = radius * angle in degrees * (PI / 180)

arc length = 6 * 160 * (PI/180)

arc length = PI * 960 / 180

arc length = PI * 5 + (60/180)

arc length = (16/3) * PI
