Question

The second part of the question is: Which describes an interval in which the function is increasing?

a) Positive slope
b) Negative slope
c) Horizontal line
d) Vertical line

Answer 1

A positive slope indicates that the line moves up the y-axis as the x-value increases, while a negative slope means that the line moves down the y-axis. In this case, a positive slope describes an interval in which the function is increasing.

Step-by-step explanation:

A positive slope indicates that the line moves up the y-axis as the x-value increases, while a negative slope means that the line moves down the y-axis. The more negative or positive the slope is, the steeper the line moves up or down, respectively. In this case, a) Positive slope describes an interval in which the function is increasing.
