Front

What is the definition of the y-intercept?

Back

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

How do you find the y-intercept of a linear equation in the form y = mx + b?

Back

The y-intercept is the value of b, which is the constant term in the equation.
