Front

What is the slope of a line parallel to the line represented by the equation y = \frac{1}{3}x - 9?

Back

The slope of a line parallel to y = \frac{1}{3}x - 9 is \frac{1}{3}.

Front

Write an equation of a line parallel to y = \frac{1}{3}x - 9 that passes through the point (15, -12).

Back

y = \frac{1}{3}x - 17.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

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

Back

They are parallel.

Front

Identify the relationship: Lines represented by y = \frac{1}{2}x + 2 and y = \frac{1}{2}x - 4.

Back

These lines are parallel.

Front

What is the slope of a line perpendicular to y = -2x + 6?

Back

The slope of a line perpendicular to y = -2x + 6 is \frac{1}{2}.

Front

Write an equation of a line parallel to y = -2x + 6 that passes through the point (-4, 6).

Back

y = -2x - 2.

Front

What type of lines intersect at a right angle?

Back

Perpendicular lines.

Front

If two lines intersect, what are they called?

Back

Intersecting lines.

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.
