Question

The equation y = 0.4x can be used to predict the number of hours, y, it takes Zula to write x number of articles for a newspaper. Which of these is the best interpretation of the slope of this linear model?

A.Zula can write410of an article in1hour.
B.It takes Zula24minutes to write each article.
C.Zula can write4articles in10hours.
D.It takes Zula0.4minute to write each article.

Answer 1

Answer: C. Zula can write 4 articles in 10 hours is the best interpretation of the slope of this linear model.

The slope of a linear equation in the form y = mx + b represents the rate of change of y with respect to x. It tells us how much y changes for a one-unit change in x. In this case, the slope of the equation y = 0.4x is 0.
