Question

Please help me thanks!!!!!

Answer 1

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 2

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
