How do you write equations for horizontal and vertical lines?

Horizontal lines go left and right and are in the form of y = b, where b represents the y-intercept, while vertical lines go up and down and are in the form of x = a where a represents the shared x-coordinate of all points.

What are the equations for the horizontal and vertical lines through 4 3?

A vertical line is of the form x=a where a is the x-intercept. A horizontal line is of the form y=b where b is the y-intercept. To get the vertical line to intersect the point (−4,−3) , it means that the x-intercept is the same x value of the point, making the equation of the vertical line x=−4 .

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.
