## How do you write an equation of a horizontal line with one point?

Generally, horizontal lines have the equation y=k where k is any constant. Given that you have a horizontal line passing through (5,−3) , we know that the only way for a horizontal line to satisfy this condition is if y would be equal to −3 .

**How do you write an equation for a horizontal line?**

Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.

**What is the equation of a horizontal line through 1 9?**

Answer: y-9 = 0 ( or ) y= 9 is the correct equation. where m = slope of the line passing through . thus you got the answer.

### What is the rule for a horizontal line?

A horizontal line is one the goes left-to-right, parallel to the x-axis of the coordinate plane. All points on the line will have the same y-coordinate. In the figure above, drag either point and note that the line is horizontal when they both have the same y-coordinate. A horizontal line has a slope of zero.

**Is Y =- 5 a horizontal line?**

The graph of a relation of the form y = 5 is a line parallel to the x-axis because the y value never changes.

**Is Y =- 2 a horizontal line?**

An Example of Graphing a Horizontal Line Graph the horizontal line y = – 2. Since we have no x-variable in the equation, it is okay to pair the y-coordinate of – 2 with any x-values.

#### What is an equation of the horizontal line that passes through 5 − 7?

y=7

Explanation: The point (a,b) is (5,7) . Therefore, the equation of the line is y=7 .

**What line is y5?**

horizontal line

Thus it is simply read y= 5. Since the slope is equal to zero, this graph would be seen as a horizontal line.

**What is the equation of the horizontal line through 1 9 )?**

## Is Y =- 3 a horizontal line?

That’s why the equation for this line is y = 3. Notice anything about all of these horizontal lines? If you answered that they’re all y = something, then you’re right. Horizontal lines are all in y = A form, where A is any real number.

**How do you write an equation for a vertical line?**

The equation for any vertical line is x= n. N is that x in the (x, y) coordinate, which means you can just forget about the y coordinate. So the equation of a vertical line for (-8, 5) would be x= -8. If you meant (8,5) then the answer would be x=8.

**What is the equation to plot a vertical line?**

The vertical line is passing through the point (−5, −2). The equation of a vertical line is in the form x = k. For vertical line, the x-coordinate of each point that lie on the line remains same.

### What are equations of horizontal and vertical lines?

Vertical lines have a undefined slope, and run parallel to the y axis. The equation for a horizontal line equals y=c , and the equation for a vertical line equals x=c. If a horizontal line crosses a vertical line the two lines would be perpendicular to one another.

**Which equation below represents a horizontal line?**

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.
