This is the equation, y is equal to six. y = 0x + b which is the same as y = b, where b is the y-intercept. Then, plug the slope into the slope-intercept formula, or y = mx + b, where "m" is the slope and "x" and "y" are one set of coordinates on the line. It will be y=9 throughout the entire graph; this means the equation is … You can't learn about linear equations without learning about slope. In this tutorial, you'll learn all about horizontal lines including their slope and what the equation of a horizontal line looks like. Substitute either point into the equation. So the line that connects these two points will look like this. So in this case, our horizontal line goes through the point (4,-6). The slope is the ratio of the change in the y-value over the change in the x-value. The equation of the horizontal line is (Type an equation. Horizontal lines always have a slope of 0. The second coordinate in each pair is the y-coordinate which are 7, and 7. Slope is the rise over the run, the change in 'y' over the change in 'x', or the gradient of a line. Remember that vertical lines only have a 'y' value and no 'x' value. What is the equation of the horizontal line passing through (3, 8)?
