What was the amount of the initial deposit that started this
savings account?

Step-by-step explanation:

12) The amount of the initial deposit is $1000

13) the slope is (y2 - y1)/(x2 - x1)

Slope = (4000 - 3000)/(6 - 4)

Slope = 1000/2 = 500

The y intercept is the value of y when x is zero. Therefore,

y intercept = 1000.

14) The equation of a straight line represented in the slope intercept form is

y = mx + c

Where

m represents slope

c represents intercept

Therefore the equation is

y = 500x + 1000

15) The slope represents rate of change in the amount saved with respect to time in months.

answer: x=3 and y=4
