I was told to make a line and find its slope with just two numbers

Question

I was told to get 5 sets of numbers and then it said to make them into a line and find the slope.

 

Exact words:

1. Collect five sets of Fahrenheit and Celsius tempuratures from five different locations. (Vary the locations so that you have a wide range of represented temperatures.)

2. Plot them on a graph with Fahrenheit and Celsius temperatures on the x and y axis.

3. Find the slope of the line.

Answer 1

Let’s pick some pairs of (℉,℃):

(32,0) (77,25) (41,5) (59,15) (-13,-25):

Slope=5/9.
