45
8(5 – 4) – 3

45/5 = 9

Step-by-step explanation:

use PEMDAS, first solve parenthesis then solve multiplication then subtract and lastly divide

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

i belive those are the ones that are under 90 degreese.
