Question

A scatterplot is used to display data where x is the amount of time, in minutes, one member can tolerate the heat in a sauna, and y is the temperature, in degrees Fahrenheit, of the sauna. Which interpretation describes a line of best fit of y = –1.5x + 173 for the data?

The member can tolerate a temperature of 173° Fahrenheit for 0 minutes
.
The amount of time the member can tolerate the heat in a sauna is 173 minutes.

The time increased 1.5 minutes for every degree Fahrenheit the temperature increased.

The time decreased 1.5 minutes for every degree Fahrenheit the temperature decreased.

Answer 1

A) The member can tolerate a temperature of 173° Fahrenheit for 0 minutes.

Answer 2

The member can tolerate a temperature of 173 degrees Fahrenheit for 0 minutes.

Explanation:

1) Using y = mx + b we have y = -1.5x + 173

2) b in this equation represents the starting temperate that a person can tolerate, which would be 173 degrees at 0 minutes
