Calculate X and Y intercepts

Front

What is the x-intercept of a function?

Back

The x-intercept is the point where the graph of a function crosses the x-axis, which occurs when y = 0.

How do you find the x-intercept of the equation y = 2x + 6?

Back

Set y = 0: 0 = 2x + 6, solve for x: x = -3. The x-intercept is (-3, 0).

Front

How do you find the y-intercept of the equation y = 4x - 8?

Back

Set x = 0: y = 4(0) - 8 = -8. The y-intercept is (0, -8).
