How Do You Write an Equation for a Horizontal Line? Vertical Line. x = -9. Better yet you’ll also discover how to use the slope intercept equation among a few different formulas, that you may use on a regular basis. Algebra 2 Horizontal & Vertical Lines. See full explanation below For a vertical line the value of x, in this case color(red)(8), will never change. Therefore the equation for a vertical line passing through this point is: x = 8 Likewise, for a horizontal line the value of y, in this case color(red)(-7), will never change. Which is also a pretty straight forward equation to solve. This will be true for any value of x. As we discussed in the last video, every line in the x-y plane has its own unique equation. When a slope is equal to zero, the line is horizontal. The line passes through the x x -axis at (a,0) (a, 0). All the points on a vertical line will share the exact same x co-ordinate. For x=a there will be a VERTICAL line at the x-coordinate of "a" For y=b there will be a HORIZONTAL line at the y-coordinate of "b" Think of this as two opposites. Is the graph of this equation a horizontal or vertical line? In order to solve a vertical line test, start off by solving the equation y = f (x). Horizontal and Vertical Lines Equations of horizontal and vertical lines only have one variable . Let’s think about a typical horizontal line. ». Therefore, it cannot be … Equation: x = b (b is the x-intercept and a constant) The equation for this graph would be: x = -3.
