Find the midpoint of the line segment joining the points ​(−1​,−2​) and ​(−3​,9​).

Step-by-step explanation:

Midpoint  =  (x₁+ x₂)/2 , (y₁ +y₂)/2

 =   [(-1)+(-3))/2] , (-2 + 9)/2

 =   (-4/2) , (-7/2)

 =   (-2 , -3.5)

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.
