What to Focus On
- ax+by+c=0 is the general form of a linear equation in two variables.
- A linear equation in two variables graphs as a straight line.
- There are five steps to draw the graph of a linear equation ax+by+c=0.
- Graphs can help find missing values in a table.
- Graphs can help identify the linear relation between x and y.
- y=mx+c is the slope-intercept form.
- A point lies on a line if its coordinates satisfy the equation.
- Horizontal and vertical construction lines help read values from a graph.
- For a point (m,-2), use y=-2 first.
Common Mistakes to Avoid
The equation of the x-axis is x = 0 and the equation of the y-axis is y = 0.
A line of the form x = a is parallel to the x-axis, and a line of the form y = b is parallel to the y-axis.
Any three points can be joined to make the graph of a linear equation, even if they do not lie on the same line.
