Insert data and it will calculate the (MAD).
From 9 P.M. to 5 A.M. the temperature dropped 20°, making the rate over 8 hours, -2.5° Per Hour. By 5 A.M., the temperature is -5° since we had to do 15 - 20. From 5 AM to 5 P.M. is 12 hours so -2.5 x 12 = -30 making 30 how much the temperature dropped between 5 A.M. to 5 P.M. Finally, our last equation is -5 - 30 making -35 our answer.
If I translated correctly into my native language, then you need to write the equation of the straight line.
y=x this is a straight line through the first and third quarters.
1) multiply by 2: y= 2x
2) to raise the function by 3 units, you need to add 3 to it. For example: y=2x to bring it up: y=2x+3
