The graph of a linear function is shown.

Question

A coordinate plane with a straight line drawn passing through (negative 5, negative 3) and (5, negative 3).
Which word describes the slope of the line?

positive
negative
zero
undefined

Answer 1

The slope of a line describes how steep the line is and the direction in which it rises or falls.

In the graph described, the line passes through the points \((-5, -3)\) and \( (5, -3)\). Since the y-coordinates of both points are the same (-3), the line is horizontal.

A horizontal line has a slope of 0.

So, the word that describes the slope of the line is \( \text{zero} \).
