Answer:
The beginning balance of Sophie's account is 75
Step-by-step explanation:
Using the slope intercept form aka
The slope of a line describes how steep a line is.
- We can see that the y-axis goes up by 25.
- 25, 50, 75, 100, 125, 150 etc
<u>$ is how much you have in your bank account.</u>
<em>We can see that Sophie starts off with 75 dollars.</em>
In the first week, we see that Sophie has 100 dollars. In the second week, we see that Sophie has 125.
<h3>how to find the slope</h3>The first week (1, 100)
The second week (2,125)
