Answer:
<h2>y = -2x - 10</h2>
Step-by-step explanation:
The formula of a slope:
We have two points (-5, 0) and (-1, -8). Substitute:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercpet
Put the value of the slope and coordinates of the point (-5, 0) to the equation of a line:
<em>subtract 10 from both sides</em>
Finally:
Answer:

The first step is to find the surface area of 1 fence post.
The formula is
Area_ends = 2 pi r^2 for the ends.
Area_body = 2*pi*r * h
Givens
r = d/2 r is the radius ; d is the diameter
r = 1/2 foot
h = 10 feet
Solution
1 fence post
Area = ends + area body
Area = 2*3.14 * (1/2)^2 + 2 * pi * r * h
Area = 2*3.14* (1/2)^2 + 2 * 3.14 * 1/2 * 10
Area = 1.57 + 31.4
Area = 32,97 square feet.
10 fence posts
10*32.97 = 329.7 square feet
Answer
10 fence posts have 329.7 square feet in area.
Answer:
50.24
Step-by-step explanation:
Area=R^2*PI
OR
Area-R*R*PI
So, Area=4*4*3.41
=50.24
Answer:
if you are required to find the equation of a straight line use the formula y-y1= m (x-x1)
y+2=-3(x-1)
y+2=-3x+3
y= -3x+3-2
y -3x+1
hope this helps
