What is the equation of a line parallel to x-axis?
The equation of line parallel to x axis is of the form y = b, and it cuts the y-axis at the point (0, b). This equation of a line y = b is a line parallel to x-axis and is at a perpendicular distance of ‘b’ units from the x-axis. And every point on this line y = b has the value of y coordinate equal to b.
How do you find the slope of a parallel line?
Explanation: First, you should put the equation in slope intercept form (y = mx + b), where m is the slope. The slope of the line is -3/8. A parallel line will have the same slope, thus -3/8 is the correct answer.
What is slope of line parallel to Y axis?
The slope of the equation of line parallel to y axis is undefined. The line parallel to y axis is at an angle of 90º to the x – axis and the slope of this line is tan90º, which is undefined.
What is the slope of x-axis?
zero
The x‐axis or any line parallel to the x‐axis has a slope of zero.
What is the formula of x-axis?
y = 0
Answer: The equation of x-axis is y = 0. The horizontal axis in a coordinate plane is represented by the x-axis. Explanation: The points on the x-axis are of the form (a, 0), where a is any real number. So, the y-coordinate of the point of the x-axis is 0.

How do you find a line parallel to the y-axis?
What is the Equation of the Line Parallel to y-axis? The equation of the y-axis is given by x = 0. The equation of the line parallel to the y-axis is x = k, where ‘k’ is any real number.
How do you find a slope?
Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .
How do you find the equation of a parallel line?
So, to find an equation of a line that is parallel to another, you have to make sure both equations have the same slope. In the general equation of a line #y=mx+b# , the #m# represents your slope value. An example of paralell lines would therefore be: (1) #y=mx+b#. (2) #y=mx +c#. With #b# and #c# being any constants.
How do you find the slope of a line perpendicular?
Find the slope of the given line. The perpendicular slope will be the opposite reciprocal of the original slope. Use the slope-intercept form (y = mx + b) and substitute in the given point and the new slope to find the intercept, b.
Do perpendicular lines have the same slope?
Parallel lines have the same slope and will never intersect. Parallel lines continue, literally, forever without touching (assuming that these lines are on the same plane). On the other hand, the slope of perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees.
How to find the slope from an equation?
1) Find the slope using m = (y2-y1)/ (x2-x1). The ordered pairs of the coordinates you have are listed as (x, y). 2) Replace the m in the slope-intercept formula with the slope you found. 3) Substitute x and y for one of the points you know to solve for the y-intercept. Pick one of the ordered pairs to put into the slope-intercept formula. 4) Solve the equation for b. Once you plug the x- and y-values as well as your slope into the formula, find the value of b in the equation. 5) Plug in the slope and y-intercept into the slope-intercept formula to finish the equation. Once you’re finished, plug in the slope for m and the y-intercept for b.
