What is the equation of a line that is perpendicular to the x-axis?

Back

The equation of a line that is perpendicular to the x-axis is of the form x = a, where 'a' is a constant.

Front

Solve for x: 2(3x + 4) + 2 = 4 + 3x

Back

x = -2

What is the equation of a line that is parallel to y = mx + b?

Back

The equation of a line parallel to y = mx + b has the same slope 'm' but a different y-intercept.

Front

What does it mean for two lines to be perpendicular?

Back

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