x and y intercepts

Front

What is the x-intercept?

Back

The x-intercept is the point where a line crosses the x-axis. At this point, the value of y is 0.

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. At this point, the value of x is 0.

Front

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

Back

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

Front

What is the x-intercept of the equation 2x + 3y = 6?

Back

(3, 0) - Set y = 0: 2x = 6, x = 3.

Front

What is the y-intercept of the equation 2x + 3y = 6?

Back

(0, 2) - Set x = 0: 3y = 6, y = 2.

Front

What does the point (0, 8) represent?

Back

It represents the y-intercept of a line, where the line crosses the y-axis at y = 8.

Front

What does the point (-2, 0) represent?

Back

It represents the x-intercept of a line, where the line crosses the x-axis at x = -2.

Front

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

Back

It means that the line crosses the y-axis at -2.

Front

What is the significance of intercepts in graphing linear equations?

Back

Intercepts help to quickly identify points on the graph and understand the behavior of the line.
