Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis.

Back

By setting y to 0 in the equation and solving for x.

Front

What is the significance of the point (0,0) in a linear system?

Back

It is the origin and can be a solution if it satisfies the equations.
