Answer 2

Answer:

2

Step-by-step explanation:

The rate of change is defined by $\frac{Rise}{Run}$ , $\frac{y_{2} - y_{1} }{x_{2}-x_{1}}$. or $\frac{Delta y}{Delta x}$.

For your question, the points are (0,4) and (2,8).

Plugging these points into the formula:

$\frac{8-4}{2-8}$

After calculations, you would end up with $\frac{4}{2}$ or 2.
