Answer:

9. 2

10. -5

Explanation:

9. The rate of change/slope can be determined by using the formula
(y_(2)- y_(1))/(x_(2)- x_(1))

In this problem, we can choose many different points. For the sake of simplicity, let's choose the first and last points. So
(x_(1), y_(1)) is (0,-5) and
(x_(2), y_(2)) is (4,3).

Plugging it in, we get:
(3-(-5))/(4-0) = (8)/(4) = 2

10. The initial value of the graph is referring to the y-intercept. In this case, it would be -5.

Hope this helps!

Answer:

9. The rate of change is 2/1 or just 2.

Explanation:

Basically, X goes up by 1 every single time. Meanwhile Y goes up by 2 every time. So you put 2 on top, and 1 on the bottom and solve.


(2)/(1) or just 2, after solving and getting rid of the 1
