Which graph could represent y, the amount owed on a car loan, as regular payments are made each month, x?
k0ka [10]

Answer:

Graph # 4

Step-by-step explanation:

If regular payments are paid each month, there would be no change in the slope of the line and the slope will be 0.

Amount owed = y

Number of car payments paid = x

So, if there is no change in y, the line will be a straight line parallel to x-axis.

\rule[225]{225}{2}

Answer:

Step-by-step explanation:

A new study suggests that waiting at least an hour after dinner before going to sleep reduces your risk of stroke by about two-thirds.

And for every 20 minutes more that you wait, stroke risk drops another 10%, says researcher Cristina-Maria Kastorini, MSc, a nutritionist at the University of Ioannina Medical School in Greece.

The study does not prove cause and effect -- only that there seems to be an association between waiting an hour or more between dinner and bedtime and reduced stroke risk.

Results of the 1,000-patient study were presented here at the European Society of Cardiology Congress 2011.
