You are trying to compare the fahrenheit and celsius scales and you have two examples: temperature a is 50 degrees celsius and 122 degrees fahrenheit. temperature b is 100 degrees celsius and 212 degrees fahrenheit. what graph models the relationship between the fahrenheit and celsius scales? what is an equation of the line in slope-intercept form?

The graph that models the relationship between the Fahrenheit and Celsius scales is attached below.

An equation of the line in slope-intercept form is F= 9/5 C+ 32. 

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
