X AND Y INTERCEPTS

Front

What is the y-intercept?

Back

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

Front

What does the y-intercept indicate on a graph?

Back

The y-intercept indicates the value of y when x is zero.

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

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

Back

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

Front

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

Back

The y-intercept can represent the starting value in a situation, such as initial cost or starting population.

Front

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

Back

The x-intercept can represent a point where a quantity reaches zero, such as when a product runs out.

Front

If a line has a y-intercept of -3, what does this mean?

Back

It means the line crosses the y-axis at the point (0, -3).
