P F Test 3 -- Linear Equations

Front

What is the equation of a line with a slope of zero?

Back

The equation of a line with a slope of zero is of the form y = b, where b is the y-coordinate of any point on the line.

Front

What does it mean for a line to be perpendicular to another line?

Back

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

Front

How do you find the slope of a line given its equation in standard form?

Back

To find the slope from the standard form Ax + By = C, rearrange to slope-intercept form (y = mx + b) where m is the slope.

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.
