A scatter plot is made to model the amount of money left to pay on a credit card. The data used for the scatter plot are shown i
n the table: Number of Months 3 5 1 2 0 4 Money Owed $1,400 $1,000 $1,800 $1,600 $2,000 $1,200 What does the y-intercept of the model represent?
2 answers:
The y-intercept of the given table is 2000.
<u>Step-by-step explanation:</u>
Write the table in the ascending order.
From the table, calculate the rise and run to find the slope of the line.
Choose points (0,2000) and (1,1800).
rise= -200 and run=1.
Slope m = -200.
The line equation is y=mx+c.
Apply the slop value in the equation,
y= -200x+c.
To find the y-intercept substitute a value in the above equation.
Substitute(1,1800),
1800 = -200(1)+c.
2000=c.
y= -200x+2000.
The y-intercept is the point where the line passes through in the vertical y-axis at the origin.
