2.3 and 2.4 Assessment

Front

What is the equation of a line parallel to y = -\frac{2}{7}x - 8 that passes through the point (-4, -3)?

Back

y = -\frac{2}{7}x - \frac{29}{7}

Front

Convert the equation y = -8x + 14 to standard form.

Back

8x + y = 14, 8x + 1y = 14

Front

What is the equation of a line parallel to y = 3x + 7 that passes through the point (-4, -3)?

Back

y = 3x + 9

Front

What is the equation of a line perpendicular to y = 3x + 7 that passes through the point (-4, -3)?

Back

y = -\frac{1}{3}x - \frac{13}{3}

Front

Convert the equation y = -\frac{9}{7}x + 2 to standard form.

Back

9x + 7y = 14

Front

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

Back

The slope is m.

Front

What is the slope of a line perpendicular to y = mx + b?

Back

The slope is -\frac{1}{m}.

Front

Define standard form of a linear equation.

Back

Standard form is Ax + By = C, where A, B, and C are integers.

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.
