Using the point-slope form, we have

y = (-3/8)(x - 3) - 3

y = (-3/8)x + 9/8 - 3

y = (-3/8)x - 15/8

Here's an explanation from PurpleMath......one of my favorite sites.....

Ah....I didn't see it as an equation.....

If it's an equation, we have

G = 5G + 8    subtract 5G from both sides

-4G = 8         divide by -4 on both sides

G = -2

We have, by the Pythagorean Theorem....

√ [x^2 - (x/4)^2] =

√ [(16x^2 - x^2) / 16]=

[√(15)/4 ] x

If G = 5

Then.....G + 8   must just be  5 + 8 = 13

If the first digit can be 0, we have 8 possibilities for each place....

So 8^4  = 4096 numbers

If the first digit can't be 0, we have 7 ways to fill the first position and 8 ways for the other three positions.

7 * 8^3 = 3584 numbers

HAHAHA !!!!

Thanks for that corrected answer, Nick

{Note that we could leave this in fractional form, as well = 13/ 24 }

sin^2(-x)+cos^2(-x)

Let -x  = θ

So

sin^2 (θ) + cos^2 (θ)  = 1   {this is just a basic identity}
