Slopes are used in many different areas that include economics, architecture and construction, trend analysis and interpretation in social, health, and market situations.
Anything that requires a scale and a graph has a use for measuring the slope. Also, in everyday life, a slope is also everywhere. Anything that includes steepness or an angle in everyday objects or observation can be measured by using the formula for the slope.
Usually, the slope is often expressed as positive or negative variables are often integers. In these situations, an undefined and zero slope occurs when either the numerator or denominator equals zero. In a zero slope, the numerator is zero. Zero divided by any non-zero denominator will result in zero. Even though the slope is zero, it is still a determined number compared to the undefined slope.

Most of your ideas focus on meaning, and I love what you write. But this one is a memory device for something that could have meaning. I want my students to really understand slope. We also talk a lot about how vertical lines have a slope that is undefined and why, so this is all taking place in a larger context.
For some students, having this memory device that immediately reminds them of what the graph looks like is a way to connect to the concept. Others like to think about the formula for calculating slope, the definition of undefined, etc…. A very helpful post. The denominator of the Undefined Slope is zero. It is because of this reason that the value of this slope is non-existent, irrespective of the numerator.
Since any numerator cannot be divided by zero, the value is always non-existent. In simple words, a Zero Slope is a slope of a horizontal line. A line on a graph which is horizontal is characterized as a Zero Slope. The numerator of a Zero Slope is always zero. Irrespective of the denominator, the value of the Zero Slope is zero. This makes the slope a determined number. The graphs of y 1 and y 2 are provided below,. Perpendicular lines have slopes that are negative reciprocals of one another.
In other words, if a line has slope m 1 , a line that is perpendicular to it will have slope,. The graphs of y 3 and y 4 are provided below,. In the next section we will describe how to solve linear equations. All rights reserved. Definition For any two distinct points on a line, x 1 , y 1 and x 2 , y 2 , the slope is,.
