Question

what is the vertical change from point a to point b? 1 what is the horizontal change from point a to point b? 3 what is the rate of change shown on the graph? give the answer as a decimal rounded to the nearest tenth, if necessary

Explanation:

Step1: Recall rate - of - change formula

The rate of change (slope) $m$ between two points is given by $m=\frac{\text{vertical change}}{\text{horizontal change}}$.

Step2: Substitute given values

We know the vertical change is 1 and the horizontal change is 3. So $m = \frac{1}{3}$.

Step3: Convert to decimal

$\frac{1}{3}\approx0.333\cdots$. Rounding to the nearest tenth, we get 0.3.

Answer:

0.3
