Intercepts of Linear Graphs

Front

What is the x-intercept of a linear graph?

Back

The x-intercept is the point where the graph crosses the x-axis, meaning the y-coordinate is zero.

Front

What is the y-intercept of a linear graph?

Back

The y-intercept is the point where the graph crosses the y-axis, meaning the x-coordinate is zero.

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What does it mean if a line has no x-intercept?

Back

It means the line is parallel to the x-axis and does not cross it.

What does it mean if a line has no y-intercept?

Back

It means the line is parallel to the y-axis and does not cross it.

Front

What is the significance of the point (0, 0) in linear graphs?

Back

The point (0, 0) is the origin, where both the x-axis and y-axis intersect.

Front

If a line passes through the origin, what are its intercepts?

Back

If a line passes through the origin, both its x-intercept and y-intercept are (0, 0).

Front

What is the x-intercept of the line represented by the equation y = 2x + 6?

Back

The x-intercept is (-3, 0), found by setting y = 0 and solving for x.

Front

What is the y-intercept of the line represented by the equation y = -x + 4?

Back

The y-intercept is (0, 4), found by setting x = 0 and solving for y.
