How Do You Graph a Vertical Line?

Problem Statment: Graph a vertical line through (2,-1)

Summary

  1. We're trying to graph the vertical (straight up and down) line that passes through the point (2,-1)
  2. The graph shows the x and y-axes, which make up the coordinate plane
  3. The x-coordinate of the point '(2,-1)' is '2'
  4. The y-coordinate of the point '(2,-1)' is '-1'
  5. Plotting another point with an x-coordinate of '2' will make it easier to draw our vertical line
  6. We chose to plot the point (2,2), but the y-coordinate could be any number

Notes

    1. We're trying to graph the vertical (straight up and down) line that passes through the point (2,-1)
    1. We're trying to graph the vertical (straight up and down) line that passes through the point (2,-1)
    2. Putting a dot on the coordinate plane where (2,-1) lies is our first step
    1. "Axes" is the plural form of "axis"
    2. Tick marks are just little lines that represent numbers

    2. Putting a dot on the coordinate plane where (2,-1) lies is our first step
    1. Since 'x=2', count two tick marks to the right of the y-axis
    2. Tick marks are just little lines that represent numbers, such as 1, 2, 3, 4, and so on
    1. Since 'y=2', count one tick mark below the y-axis
    2. Tick marks are just little lines that represent numbers, such as 1, 2, 3, 4, and so on
    1. We're trying to graph the vertical (straight up and down) line that passes through the point (2,-1)
    2. We have already plotted our point (2,-1) on the graph

    3. Plotting another point will make drawing our vertical line more like connecting the dots!

    4. In other words, every point on the line will have an x-coordinate of '2', since our point is '(2,-1)'

    5. We could pick any point, but we randomly chose '2' as the y-coordinate for our second point

    1. The point (2,2) lies along the vertical line we already drew, so we graphed our line correctly
    1. Here, we're just drawing over the dashed line we drew earlier
    2. Our two points are '(2,-1)' and '(2,2)'
    1. Other vertical lines that you graph may pass through a different x-coordinate, but they will be straight up and down like the one we just graphed
    1. In other words, you don't necessarily need to plot two points, one is enough
    1. While one point is enough to graph a vertical line, plotting more than one point will make it easier to draw the line straight up and down
