slava [35]

See the explanation

<h2>Explanation:</h2><h2></h2>

Here we have the following points:

(3,9) \ and \ (-3,-9)

The point-slope form of the equation of a line is:

y=ax+b \\ \\ \\ a:Slope \\ \\ b:y-intercept

So the slope can be found as:

a=\frac{-9-9}{-3-3} \\ \\ a=\frac{-18}{-6} \\ \\ a=3

So:

y=3x+b \\ \\ \\ Finding \ b: \\ \\ For \ x=3, \ y=9: \\ \\ \\ So: \\ \\ 9=3(3)+b \\ \\ b=9-9 \\ \\ b=0

So the equation is finally:

y=3x

This line passes through and is shown below.

The diameter of the moon is 2160 miles. A model has a scale of 1in : 150mi. What is the diameter of the model?

So you would take 2160/150 because you need the Circumference

This will give you 14.4 and you will need to device that by pie to find Diameter

Answer: 14.4

Sorry no need for Pie in this equation I just realized it was a scale. 

Sorry about that!
