X and Y intercepts

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 from a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

If a line has a y-intercept of -1, what does this mean?

Back

It means the line crosses the y-axis at the point (0, -1).
