1. Graphing Linear Equations Including Horizontal and Vertical Lines Presley Lozano, Chloe Husain, and Savannah Nguyen

2. Vocabulary Domain: the set of values of the independent variables Range: the set of y values of a function or relation Constant function: the function is the form of y=x (f) or the constant The x and y plane is formed by the x-axis and the y-axis Horizontal line: the line is perfectly flat and level there is no slope Vertical line: like that is straight up and down

3. How to Find the X an Y Intercepts X and Y Intercepts: The x-intercept is where the graph crosses the x- axis, and the y-intercept is where the graph crosses the y-axis The x-intercept: is a point is a point on the graph where the y is zero and the y-intercept is the pint on the graph where the x is zero Ways to solving: Plug in the zero for the one you aren't solving for, in other words when you're solving for x you plug in zero for y. Vise versa when you are solving for y you plug in zero for x.

4. How to Graph Horizontal Lines A line that is parallel to the x-axis is going to be your horizontal line. When graphing horizontal line, you will be given the y-value such as something like y=4. This means the coordinating points that have 4 as the y will be on the horizontal line. Example: (5,4) (10,4) and(-24,4) will all be on this horizontal line.

6. How to Graph Vertical Lines Next is how to graph a vertical line, which is a line that is parallel to the Y axis. You will be giving a value for x when finding a vertical line. You might be given at x=0 which means only point with the x value of zero will be on this line. Example: (0,3) (0,6) and (0,10) will all be on this vertical line.
