x-intercept and y-intercept

Front

What is the x-intercept?

Back

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

Front

What is the y-intercept?

Back

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

Front

How do you find the x-intercept from an ordered pair?

Back

To find the x-intercept from an ordered pair, look for the pair where y is equal to zero.

Front

How do you find the y-intercept from an ordered pair?

Back

To find the y-intercept from an ordered pair, look for the pair where x is equal to zero.

Front

True or False: The x-intercept of a function ALWAYS occurs where y is equal to zero.

Back

True

Front

True or False: The y-intercept of a function ALWAYS occurs where y is equal to zero.

Back

False

Front

Given the ordered pairs (8,10), (3,-4), (0,8), (4,-3), (9,0), what is the x-intercept?

Back

(9,0)

Front

Given the graph, if the x-intercept is 1, what does this mean?

Back

It means the graph crosses the x-axis at the point (1,0).

Front

If a function has a y-intercept of -3, what does this indicate?

Back

It indicates that the graph crosses the y-axis at the point (0,-3).

Front

What is the significance of the x-intercept in a real-world context?

Back

The x-intercept can represent a point where a quantity reaches zero, such as profit or population.
