How do you write an equation for a horizontal line?Horizontal Lines
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.
How do you write the equation of a vertical line?Each point on a vertical line has the same x -coordinate. If two points have the same x -coordinate, c , the equation of the line is x=c . The x -intercept of a vertical line x=c is the point (c,0) .
What is a vertical equation?Vertical lines have equations that look like this: x=b where b is a real number. In this equation, b is the fixed value that x must take, despite the varying y-values.
