Write the equation of a horizontal line that passes through the point (-2, 2).
Solution:
Given, the point is (-2, 2)
We have to find the equation of a horizontal line passing through the given point.
A horizontal line is a straight line that is parallel to the x-axis in the coordinate plane.
The slope of the horizontal line is zero.
The equation of the horizontal line passing through a point (a, b) is given by
y = b
At point (-2, 2)
y = 2
Therefore, the equation of a horizontal line is y - 2 = 0.
Example:
What is the equation of a horizontal line passing through the point (1, -5)?
Solution:
Given, the point is (1, -5)
We have to find the equation of a horizontal line passing through the given point.
A horizontal line is a straight line that is parallel to the x-axis in the coordinate plane.
The slope of the horizontal line is zero.
The equation of the horizontal line passing through a point (a, b) is given by
y = b
At point (1, -5)
y = -5
Therefore, the equation of a horizontal line is y + 5 = 0.
Write the equation of a horizontal line that passes through the point (-2, 2).
Summary:
The equation of a horizontal line passing through the point (-2, 2) is y - 2 = 0.
