Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

tangare [24]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =-2\\y_{1} =4\\x_{2} =6\\x_{1} =-2$

^^^Plug these numbers into the formula for slope...

$\frac{-2 - 4}{6 - (-2)}$

$\frac{-6}{8}$

^^^Can be further simplified to...

$\frac{-3}{4}$

^^^This is your slope

Hope this helped!

Answer:

<em><u>y = d + a · cos(bx - c) ⇒ y = -4cos(4/3x)</u></em>

a = -4
b = 4/3
c = 0
d = 0

Amplitude = |a| = |-4| = 4

Period = $\frac{2\pi }{b} =\frac{2\pi }{\frac{4}{3} } =2\pi *\frac{3}{4} =\frac{3}{2} \pi$

The wheels on a bike have a 12 inch diameter. What is the circumference? c=Pi,d

aniked [119]

Hey!

To find circumference, yo multiply $\pi$ by diameter.

$Diameter = 12 \\ \pi = 3.14$

Multiply

$3.14 \times 12 = 37.68$

The circumference is 37.68 inches

Hope this helps! :)
