Legend has it that a bull sasquatch in rut will howl approximately 9 times per hour when it is 40°f outside and only 5 times per hour if it is 70°f. assuming that the number of howl's per hour, n, can be represented by a linear function of temperature fahrenheit, find the number of howl's per hour he'll make when it is only −20°f outside. (round your answer to the nearest whole number.)

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
