Finding X and Y Intercepts

Front

What is the x-intercept of a graph?

Back

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

Front

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

What is the y-intercept of a graph?

Back

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

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

Given the equation y = 2x + 6, find the x-intercept.

Back

The x-intercept is ( -3, 0 ).

Front

Given the equation y = -x + 4, find the y-intercept.

Back

The y-intercept is ( 0, 4 ).

Front

What does the point (12, 0) represent in terms of intercepts?

Back

The point (12, 0) represents the x-intercept of the graph.

Front

What does the point (0, -3) represent in terms of intercepts?

Back

The point (0, -3) represents the y-intercept of the graph.

Front

If a line has an x-intercept of (5, 0), what does this indicate about the line?

Back

It indicates that the line crosses the x-axis at x = 5.

Front

If a line has a y-intercept of (0, -2), what does this indicate about the line?

Back

It indicates that the line crosses the y-axis at y = -2.
