Front

What is the slope-intercept form of a linear equation?

Back

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Front

What does it mean for a line to pass through a point (x, y)?

Back

A line passes through a point (x, y) if the coordinates satisfy the equation of the line.

Front

What is the significance of the y-intercept in a linear equation?

Back

Front

How can you determine if a point lies on a given line?

Back

Substitute the x-coordinate of the point into the equation of the line. If the resulting y-value equals the y-coordinate of the point, it lies on the line.

What is the formula for the point-slope form of a linear equation?

Back

Front

How do you convert from point-slope form to slope-intercept form?

Back

Front

What is the relationship between parallel lines in terms of slope?

Back

Parallel lines have the same slope but different y-intercepts.
