Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

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

Back

False. The y-intercept occurs where x is equal to zero.

Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis, represented as (x, 0).

Front

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

Back

Set x = 0 in the equation and solve for y.

Front

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

Back

Set y = 0 in the equation and solve for x.

Front

What does the point (0, 3) represent on a graph?

Back

It represents the y-intercept of the line, where the line crosses the y-axis at y = 3.

Front

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

Back

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

Front

Given the ordered pair (9, 0), what does it signify?

Back

It signifies the x-intercept of the function.

Front

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

Back

The y-intercept can represent the starting value of a situation when x is zero.

Front

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

Back

The x-intercept can represent the point at which a situation reaches a value of zero.
