Ok so the formula for point-slope is:

m=slope
y1 = y point that's given
x1 = x point that's given
The problem says "use the point (-1,-4)"
so we will put it into our equation.
(-1,-4)
-1 is our x, and -4 is our y, now we can put it into the equation.

Now we need to find the slope using:

y2=4
x2=3
y1=-4
x1=-1
m=2
So the answer is..

Answer:
263.76 feet
Step by step explanation:
Circumference of a circle = pi x d
Given
Diameter d =84 and
Pi = 3.14
Therefore
Circumference = 3.14 x 84
= 263.76 feet
Function a is linear, the equation is y = 5/3x or y=5/3x+0
