Question

tajiri opens a savings account. each week he adds the same amount of money to his account. the graph represents the amount in his bank account, y, after x weeks. what is the change in horizontal distance from (2, 30) to (4, 60)? label the change in horizontal distance on the slope triangle.

Explanation:

Step1: Identify horizontal coordinates

The x-values are $x_1=2$ and $x_2=4$.

Step2: Calculate horizontal change

Subtract initial from final x-value.
$\Delta x = x_2 - x_1 = 4 - 2$

Answer:

The change in horizontal distance is 2 (representing 2 weeks). This value labels the horizontal side of the slope triangle between the two points.
