Intercepts of a Line
When we graph a line, the x-intercept and the y-intercept are two points
that are often easy to find and use.
x-intercept and y-intercept
|The x-intercept of a line is the point
where the line crosses the x-axis.
The x-intercept has the form (a, 0),
where a is a constant.
The y-intercept of a line is the point
where the line crosses the y-axis.
The y-intercept has the form (0, b),
where b is a constant.
We can use the graph to find the intercepts of the equation 3x + 2y = 6.
The x-intercept is the point (2, 0).
The y-intercept is the point (0, 3).
We can use intercepts to graph a line.
