Front

What are the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

How do you solve for a in the equation a = pw?

Back

a = w/p.

Front

What are the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

If the slope of a line is -3 and the y-intercept is 4, what is the new equation if the slope is multiplied by -2 and the y-intercept is shifted down 6 units?

Back

y = 6x - 2.

Front

What is the slope of a line perpendicular to a line with a slope of 5?

Back

The slope of a line perpendicular to 5 is -1/5.

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

What is the formula for the slope between two points (x1, y1) and (x2, y2)?

Back

Slope = (y2 - y1) / (x2 - x1).

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

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

How do you find the y-intercept of a linear equation in slope-intercept form?

Back

The y-intercept is the value of y when x = 0, represented as 'b' in y = mx + b.
