The slope is -4
The change in y over the change in x is -8/2 from x= 1 to x= 3 and from x= 3 to x= 5. -8/2 simplifies to -4

Show that line passing through points (3,-2) and (-4,-2) is a horizontal line

Ierofanga [76]

Step-by-step explanation:

horizontal lines will have a gradient(m) of 0

so if m=0 , the line is horizontal

formula to find m:

m=y2-y1 / x2-x1

insert coordinates into formula

$m = \frac{ - 2 - ( - 2)}{ - 4 - 3} \\ \\ m = \frac{ - 2 + 2}{ - 7} \\ m = \frac{0}{ - 7} \\ m = 0$

As m=0 , therefore it is a horizonta line.

hope this helps..

Hello,

If Mr. Trujilo wants to pain only the wall:

Wall:

12.5 feet x 8.5 feet = 106.25 ft2

Door

5 feet x 6.75 feet = 33.75 ft2

Wall - Door = 106.25 ft2 - 33.75 ft2 = 72.5 ft2

The Earth has a diameter

mrs_skeptik [129]

Answer:

<em>L = 24,873.6 miles</em>

Step-by-step explanation:

<u>Length of the Circumference</u>

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

$L =2\pi\cdot r$

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

$L =2\pi\cdot 3,958.75\ miles$

L = 24,873.6 miles
