The graph of y=15 is a horizontal line at y = 15.
The equation y=15 represents a horizontal line parallel to the x-axis at a constant y-coordinate of 15. This type of line is described as a horizontal line and is the graph of a constant function where y is always equal to 15, regardless of the value of x.
Therefore, the correct choice among the options provided is:
b. horizontal line
This line runs infinitely along the y-axis at y = 15 without intersecting the x-axis. It is parallel to the x-axis and has a slope of 0 because it does not exhibit any change in the y-coordinate for any value of x. Thus, the graph of y=15 is a horizontal line at y = 15. Complete Question:
Describe the graph of the line y = 15.
Group of answer choices
a.crosses the x-axis
b.horizontal line
c.vertical line
d.line with slope of 15
