If a=b+3, express a+b in terms of b and evaluate the expression when b=3​

Step-by-step explanation:

a=b+3

when b=3

a+b= b+3+b= 2b+3 = 6+3=9

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
