Slope and y intercept
morpeh [17]

Answer:

y=\frac{25}{1}x+75

The beginning balance of Sophie's account is 75

Step-by-step explanation:

Using the slope intercept form aka y=mx+b

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>

slope formula\\m=\frac{rise(y)}{run(x)}=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

The first week (1, 100)

The second week (2,125)

(x_{1}, y_{1})= 1, 100\\(x_{2}, y_{2})= 2, 125\\m=\frac{125-100}{2-1}=\frac{25}{1}    \\Up 25 (aka, 1 line), over 1(aka 2 lines)
