A formula is a way of an expression in order to make solving a question easier than ever.
*that's what I think . ...*
Since the slope is -2 we know that m=-2. Now use the standard form of y=mx+b and plug in the coordinates (-8,2). We know y=2, x=-8, and m=-2. Therefore we get 2=-2(-8)+b. Now solve for b and you get -14. Therefore, the equation is y=-2x-14.
Hope this helped!
Here is the anwer to your question ,
n+4•5
For number 7.
Supplementary angles sum to 180.
2x+4x=180
6x=180
x=30
The two angles are 2x and 4x or 60 and 120
