What does it mean for lines to be intersecting in a system of equations?

Back

It means that the lines cross at one point, which is the unique solution to the system.

What does the slope of a line represent?

Back

The slope indicates the steepness of the line and the direction it goes (rise over run).

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

What is the difference between parallel and intersecting lines?

Back

Parallel lines never intersect and have the same slope, while intersecting lines cross at one point.
