Remember that as your y value will always have the same value, -1, the equation which you should use for your given examples y= -1. slopes of horizontal and vertical lines The slope of a line is the ratio of rise to run for any two points on the line. A horizontal asymptote of a graph is a horizontal line of the form y = b, where b is a constant, that is an asymptote of the graph. Definition: Vertical Line A vertical line is the graph of an equation that can be written in the form x = a. x = a. A vertical line also differs from a horizontal line as unlike a horizontal line which features a slope, a vertical line doesn’t have a slope. Remember that vertical lines only have a 'y' value and no 'x' value. Starting with looking at coordinates to spot the link, then identifying 7 lines, then drawing given lines onto a graph.
