Who is Steeper?
In mathematics, the slope or gradient of a line is a number that describes the direction and steepness of the line. Often denoted by the letter m, slope is calculated as the ratio of the vertical change to the horizontal change ("rise over run") between two distinct points on the line, giving the same number for any choice of points. A line descending left-to-right has negative rise and negative slope. The line may be physical – as set by a road surveyor, pictorial as in a diagram of a road or roof, or abstract. The steepness, incline, or grade of a line is the absolute value of its slope: greater absolute value indicates a steeper line. Direction is defined as follows: An increasing line goes up from left to right, and has positive slope: m > 0 {\displaystyle m>0} . A decreasing line goes down from left to right, and has negative slope: m < 0 {\displaystyle m<0} ....
