Parallel lines

Front

What is the slope of a line parallel to y = 1/2x + 9?

Back

1/2

Front

What is the slope of a line parallel to y = 2x - 7?

Back

2

Front

Are the lines y = -4x - 9 and y = -4x + 12 parallel?

Back

Yes, they are parallel.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.

Front

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

Back

Convert both equations to slope-intercept form (y = mx + b) and compare their slopes.

Front

What is the slope of the line represented by the equation 4x + 2y = 10?

Back

The slope is -2.

Front

If two lines have the same slope, what can be said about their y-intercepts?

Back

If they have the same slope and different y-intercepts, they are parallel.

Front

What is the slope of a line parallel to y = -3x + 5?

Back

-3

Front

How do you convert the equation 4x + 2y = 10 to slope-intercept form?

Back

Subtract 4x from both sides and then divide by 2 to get y = -2x + 5.

Front

What is the relationship between the slopes of parallel lines?

Back

The slopes of parallel lines are equal.
