The average low temperature in Boston in January is -5°C. The average low temperature in Chicago in January is -11°C.
Part A
Write a subtraction expression to represent the difference between Boston's
average low temperature in January and Chicago's average low temperature in
January. Then write the subtraction expression as an addition expression.

-11 - -5 = 6

6 + 5 = 11

Step-by-step explanation:

The average temperature in Chicago is -11. The average temperature in Boston is -5.

Subtract -5 from -11.

You get the number -6.

Make an addition sentence.

-6 + -5 = 11

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
