Final answer:
The steepness of a line on a graph is not called the rise, but rather the slope, which reflects the ratio of the vertical change to the horizontal change or 'rise over run.' The slope determines how steep a line is, with positive slopes indicating an upward tilt and negative slopes indicating a downward tilt.The statement is false.
Step-by-step explanation:
The statement that the steepness of a line on a graph is called the rise is False. The steepness of a line is accurately referred to as the slope of the line. Slope is a measure of how much a line goes up (rise) or across (run) on a graph. To understand slope, it's helpful to remember that it is calculated as 'rise over run', which is the change in the vertical direction (rise) divided by the change in the horizontal direction (run).
When the slope of a line increases, the line gets steeper; conversely, when the slope decreases, the line becomes flatter. This applies to both positive and negative slopes. A positive slope means the line is moving upward as it goes from left to right, while a negative slope signifies a downward trend. A slope of zero indicates a flat, horizontal line, and a vertical line has an undefined slope since division by zero is not possible.
