y = 4x + 12.

Front

What is the equation of a line parallel to the y-axis that goes through the point (-3, 5)?

Back

x = -3.

Front

If two lines have the same slope, what can we say about them?

Back

They are parallel.

Front

If two lines have slopes that are negative reciprocals of each other, what can we say about them?

Back

They are perpendicular.

Front

What is the general form of the equation of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the term 'slope' represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x.

Front

How can you determine if two lines are parallel using their equations?

Back

Check if their slopes are equal.

Front

How can you determine if two lines are perpendicular using their equations?

Back

Check if the product of their slopes is -1.
