Question

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?

Answer 1

line between \((50,122)\) and \((100,212)\) slope is
\[\frac{212-112}{100-50}=\frac{90}{50}=\frac{9}{5}\]

Answer 2

equation you get from the point slope formula, use \((y-122)=\frac{9}{5}(x-50)\) and get
\[y=\frac{9}{5}x+32\] or if you prefer
\[F=\frac{9}{5}C+32\]
