Which property of real numbers is shown below ? -6+6=0

Additive inverse

Step-by-step explanation:

Additive inverse property of real numbers is shown below.

-6 + 6 = 0

Here - 6 is the Additive inverse of 6.

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
