Answer:
9. 2
10. -5
Step-by-step explanation:
9. The rate of change/slope can be determined by using the formula [tex]\frac{y_{2}- y_{1}}{x_{2}- x_{1}}[/tex]
In this problem, we can choose many different points. For the sake of simplicity, let's choose the first and last points. So [tex](x_{1}, y_{1})[/tex] is (0,-5) and [tex](x_{2}, y_{2})[/tex] is (4,3).
Plugging it in, we get: [tex]\frac{3-(-5)}{4-0} = \frac{8}{4} = 2[/tex]
10. The initial value of the graph is referring to the y-intercept. In this case, it would be -5.
Hope this helps!
