What would be the equation containing the points (-8,-15),(-3,0),(2,15)

lys-0071 [83]

Answer:

$y=3x+9$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take the points

(-8,-15),(-3,0)

substitute in the formula

$m=\frac{0+15}{-3+8}$

$m=\frac{15}{5}$

$m=3$

step 2

Find the equation in point slope form

$y-y1=m(x-x1)$

we have

$m=3$

$point\ (-3,0)$

substitute

$y-0=3(x+3)$

step 3

Convert to slope intercept form

$y=mx+b$

$y-0=3(x+3)$

apply distributive property right side

$y=3x+9$

The diameter of the earth

Roman55 [17]

Answer:

25,132.74 miles

Step-by-step explanation:

Hello!

We are basically asked to find the circumference of the Earth's cross-section.

Circumference: $C = 2\pi r$

We can replace 2r with the diameter, because the diameter is 2 times the radius.

Multiply the Diameter by pi:

$C = \pi D$
$C = 8000\pi$
$C = 25,132.7412287183 \approx 25,132.74$

It is around 25,132.74 miles around.
