Answer:
y=1/4x+4
Step-by-step explanation:
to find the slope use (y2-y1)/(x2-x1)
(5-6)/(4-8)= 1/4
1/4 is your slope
to find the b in y=mx+b, plug in 1/4 for m and choose one of the points to plug in for x and y
I will use (4, 5)
5=1/4(4)+b
5=1+b
4=b
the final equation in y=1/4x+4
hope this helps!

Answer:
12 hours
Step-by-step explanation:
Let Theo's siste can paint a fence in x times
Given.
Theo can paint a fence three times as fast as his sister can. Working together, they can paint a fence in 9 hours.

Apply cross multiplication

Theo’s sister to paint the fence in 12 hours.
We know that
in a unit circle the radius is 1
therefore
[Length of a circumference]=2*pi*r------> 2*pi
if 2pi radians in a circle unit has a length of ------------> 2*pi
2pi/3 radians----------------------------> X
X=2pi/3
the answer is 2pi/3
