What is a y-intercept?

Back

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

Front

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

Back

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

Front

What does it mean if two lines are parallel when graphing a system of equations?

Back

It means there is no solution, as the lines never intersect.
