Flashcardizz Identifying Parallel and Perpendicular Lines

Front

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

Back

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

Front

What is the slope of a line parallel to a line with slope m?

Back

The slope of a line parallel to a line with slope m is also m.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

How do you determine if two lines are perpendicular?

Back

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

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

Convert the equation 3x + 4y = 32 to slope-intercept form.

Back

y = -3/4x + 8.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

How can you determine if a triangle is a right triangle using coordinates?

Back

You can use the distance formula to find the lengths of the sides and then apply the Pythagorean theorem.

Front

What is the distance formula?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the midpoint formula?

Back

The midpoint formula is M = ((x1 + x2)/2, (y1 + y2)/2).
