You could know what steep is, yet when you’re inquiry “What is the slope of a horizontal line?”, her mind goes blank. Fine walk you v this answer, whereby it comes from, and also how to calculation slope in other situations.

You are watching: Horizontal lines have a slope of

The steep of a Horizontal and also Vertical Line

The steep of a horizontal line is zero while the steep of a vertical heat is undefined.

Slopes stand for a line"s ratio of vertical adjust to horizontal change. Since horizontal and vertical present remain continuous and never rise or decrease, they"re merely straight lines.

Horizontal lines have no steepness in ~ all. Because any kind of calculation that the slope of horizontal lines way dividing zero by one more number, the slope of a horizontal line is always zero.

A upright line, on the other hand, is calculation by dividing a number by zero. Since you can’t divide by zero, upright lines constantly have an unknown slope.

Finding the slope of a Line

Now that we’ve learned that the steep of a horizontal line is zero, let"s learn how to uncover the slopes that other linear equations.

Linear equations composed as y=mx+b room in slope-intercept form. The m represents the slope and also the b to represent the y-intercept.

Slopes are frequently written in fraction kind to represent how much activity there is between each given collection of points. The molecule of the slope represents the increase in y-values and also the denominator represents an increase in x-values. The steep of the equation below is

The steep of the line determines just how steep a heat is and also at what edge the line will hit that is x-axis and also y-axis. That will likewise determine whether the line will climb or fall. If you have a hopeful slope, prefer in equation 1, your values room increasing and also the line will rise. If you have a an unfavorable slope, prefer in equation 2, they room decreasing and also the line will fall.

Note that as result of the essence 2 in equation 1, ours line the cross the y-axis at (0, 2).

The prestige of Slopes

Slopes are an essential part the understanding and also graphing a direct equation. As soon as you watch a horizontal, you deserve to conclude the slope is zero. However, the steep of a vertical line is undefined.

When you watch an angled line on a graph, you deserve to use its readjust in horizontal and also vertical worths to recognize the slope.
