There are no comments. The Slope (also called Gradient) of a straight line shows how steep a straight line is. The slope is a measure of how the line angles away from the horizontal.One can also think of slope as the "slant" of a line The slope of a line is a rate change and the letter m is used to represent slope. All horizontal lines have slope 0. Slope. So how do we find the slope of the horizontal line y = 4? Sometimes, we will be given one point and the slope of the line, instead of its equation.

Example 1: If line l has slope 3/4, then (a) any line parallel to l has slope ___, and (b) any line perpendicular to l has slope ___. The slope of a vertical line is undefined since there is 0 horizontal change, so. In this chapter, we graphed lines by plotting points, by using intercepts, and by recognizing horizontal and vertical lines. }\hfill & & \phantom{\rule{5em}{0ex}}& & \text{The run is 3. answer mamaya na po ipapass. The slope of a horizontal line = 0, not undefined. $$\begin{array}{ccccc}\text{What is the rise? Solution : By considering the above points, the x-coordinate values are same. Try thisAdjust the line below by dragging an orange dot at point A or B. Now, we’ll consider a vertical line, the line. For every two hours that pass, you move zero miles. More From Reference. Equation of Horizontal Line always takes the form of y = k where k is the y-intercept of the line.For instance in the graph below, the horizontal line has the equation y = 1 As you can see in the picture below, the line goes perfectly sideways at y =1. Get the answers you need, now! The slope of a horizontal line is actually 0. The lines are horizontal (flat) and so have no “steepness” to measure. We locate any two points on the line. 0 divided by anything is still equal to 0, and therefore, our horizontal line's slope is 0. It’s not as interesting as other functions, but it doesn’t get much simpler than this. The Slope-Intercept Form of a Line. This modified article is licensed under a CC BY-NC-SA 4.0 license.

A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y also decreases. Slope of a Horizontal Line. The line is horizontal. A horizontal line has a horizontal change but the vertical change is zero. Division by 0 is not defined. 0 divided by any number is 0, giving you a slope of 0. The slope of any vertical line is undefined. Go back to your second-story search for that working bathroom (too many trips to the punch bowl? Because a horizontal line does not change in y-value with changes in x-value, its slope may be calculated as zero divided by any number. Any line of the form \(y = c$$, where $$c$$ is some real number, will have a slope of zero. Slope of {{\, - 3} \over 2} and through the point \left( { - 1,\, - 1} \right). By using ThoughtCo, you accept our, The Slope of the Regression Line and the Correlation Coefficient, How Slope and Elasticity of a Demand Curve Are Related, Isometric Paper, Math Charts, Grids, Graph Paper, Formula for the Normal Distribution or Bell Curve, B.B.A., Finance and Economics, University of Oklahoma. There are four different types of slope that all are depending on the direction of the line. Slope = Change in YChange in X : Have a play (drag the points): Examples: The Slope of this line = 3 3 = 1. Don't want to keep filling in name and email whenever you want to comment? Now, we’ll consider a vertical line, the line. The slope of a linear function The steepness of a hill is called a slope. Questions asked by the same visitor .

Example 2 : Write an equation of the line which passes through (-4, 1), (-4, 7). 0 divided by anything is 0, so the slope of a horizontal line … The Slope of a Tangent Line: The horizontal tangent lines are parallel to the x-axis. The slope is undefined. ), the fraction representing slope has a zero in its numerator.
