Answer:
linear
Step-by-step explanation:
The x-values all differ by 1, which is to say they are equally-spaced. The corresponding y-values all differ by -3. When (first) differences of equally-spaced values of y are constant, the function is of first degree, which is to say it is linear.
___
If second differences are non-zero and constant, the function is of second degree, quadratic.
Please see pic, I'd solved in it.
Square root of 64= 8
Cube root of 64= 4
8/4= 2
15 miles/hour x 2/3 hour = 30/3 = 10 miles
