Terminology
- horizontal line
- vertical line
Task goals
- Write the equation of a horizontal line ($y=$ constant) or a vertical line ($x=$ constant) through a given point.
- Identify whether a given equation of the form $x=c$ or $y=c$ describes a horizontal or a vertical line.
- Find the equation of a horizontal or vertical line from a set of coordinate points or a table where one coordinate stays fixed.
- Describe a line as parallel to the $x$-axis or parallel to the $y$-axis through a given point.
- State that a horizontal line has a gradient of $0$ and that a vertical line has an undefined gradient.
- Write the equations of all four sides of a rectangle or square from its vertices, using horizontal and vertical line equations.
- Explain why a vertical line such as $x=5$ cannot be written in the form $y=mx+c$, and compare the positions of lines like $y=-6$ and $x=-6$.
Teaching guidance
- Students should know x=c, y=x form.
- Better students should be able to describe the gradient properties of these lines.
