Which of the following is correct?

A) The slope of a line will be infinite for a horizontal line.
B) The slope of a fairly flat upward-sloping line will be a large negative number.
C) The slope of a line will be a negative number for a downward-sloping line.
D) The slope of a steep upward-sloping line will be a small negative number.

Slope

In mathematics, the measure of the steepness or incline of a line, often calculated as the ratio between the change in the y-value to the change in the x-value.

Horizontal Line

In geometry and graphing, a straight line that runs left to right (parallel to the x-axis) and has a slope of zero, indicating no change in the y-value across different points on the line.

Upward-sloping Line

A graphical representation often used to show a positive relationship between two variables on a graph, indicating that as one variable increases, the other does as well.
