Miguel reads that the average low temperature today is −4.2°F and that the average high temperature is 9.1º F. Miguel plots the points on the number line to determine the temperature change between these two readings.

What is the temperature change?
° F
Thank you

13.3°F

Step-by-step explanation:

The change in today's temperature between the two readings as measured by Miguel is 13.3°F

Miguel's temperature readings :

Average low temperature = -4.2°F

Avetage high temperature = 9.1°F

The change in temperature is the difference between the two temperature readings :

Average high temperature - Average low temperature

(9.1 - (-4.2))°F

(9.1 + 4.2)°F = 13.3°F

Hence, the change in temperature reading = 13.3°F
