Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph. It represents the value of y when x is 0.

What does the y-intercept represent in a linear equation?

Back

In a linear equation of the form y = mx + b, the y-intercept is represented by 'b', which is the value of y when x is 0.

Front

If a line has a y-intercept of 4, what does this mean?

Back

It means that when x = 0, the value of y is 4.

Front

How do you find the y-intercept from a graph?

Back

To find the y-intercept from a graph, look for the point where the line crosses the y-axis.

Front

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

Back

The y-intercept is 3, which is the value of y when x = 0.

Front

In the equation y = -x + 5, what is the y-intercept?

Back

The y-intercept is 5.

Front

If a line has a negative slope, how does it affect the y-intercept?

Back

The slope does not affect the y-intercept directly; the y-intercept is still the point where the line crosses the y-axis.

Front

What is the y-intercept of the equation y = 0.5x - 2?

Back

The y-intercept is -2.

Front

In a real-world scenario, what does the y-intercept represent?

Back

In real-world scenarios, the y-intercept can represent a starting value or initial condition before any changes occur.
