The solution set for the last equation represents the set of all days when the towns have the same average high temperature.
- The hotness of matter or radiation is expressed by the physical quantity known as temperature. The average air temperature for a specific time period, often a day, a month, or a year, as measured by a thermometer that has been properly exposed.
- P(t) is the average high temperature, in degrees Celsius, of Paityn's town on t days.

- V(t) is the average high temperature, in degrees Celsius, of Vince's town on t days.

- So, P(t) = V(t) represents the set of all the days when both towns have the same average high temperature.

Good luck!
a = ( 1 , 6 )
b = ( 4 , 9 )

Now just need to put the coordinates in the above equation :



And we're done...♥️♥️♥️♥️♥️
