Front

What is the slope-intercept form of a line?

Back

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

Front

How do you find the slope of a line parallel to another line?

Back

The slope of a line parallel to another line is the same as the slope of the original line.

Front

Find the equation of the line that passes through the point (2,5) and is parallel to the line y = 2x + 3.

Back

y = 2x + 1

Front

What is the midpoint formula for a line segment with endpoints (x1, y1) and (x2, y2)?

Back

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

Front

Find the midpoint of the segment with endpoints (-4, 5) and (7, -9).

Back

M = (\frac{3}{2}, -2)

Front

What does it mean for two lines to be parallel?

Back

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

Front

How do you determine if two angles are complementary?

Back

Two angles are complementary if the sum of their measures equals 90 degrees.

Front

Find m∠D if m∠D + 116° = 180°.

Back

m∠D = 64°.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

If a line has a slope of 3, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to it would be -1/3.
