The answer is 13.
To solve this question, you need to determine the slope of the function. if howl is y and the temperature is x of the graph, the slope would be:
9-5/(40-70)= 4/-30= -2/15
Using one of the point and the slope, you can find the number of howl
-2/15= 9-y/40-(-20)
9-y= -2/15 * 60
9-y= -4
y= 9+4= 13
Answer:
using the y intercept formula
What grade you in and what unit lesson is this, I might be able to help you. I go to the same school.
Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
