Slope; 2 1/2

Step-by-step explanation:

Let us apply the slope equation ( y2 - y1 )/ ( x2 - x1 );

Here y2 stands for ⇒ 4, y1 stands for ⇒ - 1, x2 ⇒ 1, and x1 ⇒ -1,

( 4 - ( - 1 ) )/ ( 1 - ( - 1 ) ),

( 4 + 1 )/ ( 1 + 1 ),

Slope; 5/ 2

5/2 or 2 1/2

Step-by-step explanation:

slope =rise/run

5/2

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
