(2·5)^2 -3·3^2 = 10^2 -3·9 = 100 -27 = 73
___
Or, you can let a calculator or spreadsheet evaluate the function for you.
Answer: y-8=-1(x+3)
the formula for pain-slope form is:

(where

=a known y coordinate &

=a known x coordinate.
Now just plug in the data...
y-8=-1(x--3)
y-8=-1(x+3)
Cos Ф=side adjacent/ hypotenuse
In this case:
cos Ф=3/5
Answer: cos Ф=3/5
Step-by-step explanation:
a 9/2 is the correct answer.
