Semester 1 Finals Abbreviated

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-coordinate with respect to the x-coordinate, indicating how steep the line is.

Front

What is the relationship between two lines with slopes m1 and m2 if m1 * m2 = -1?

Back

The two lines are perpendicular.

Front

What is the slope of a line parallel to a line with slope m = 4?

Back

The slope of a line parallel to m = 4 is also 4.

Front

What is the definition of congruence in geometry?

Back

Congruence means that two figures have the same shape and size.

Front

What property is used when replacing a variable with a number in an equation?

Back

Substitution Property.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of their measures is 90 degrees.

Front

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

Back

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

Front

What does it mean if two lines are parallel?

Back

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

Front

What is the Symmetric Property in mathematics?

Back

If a = b, then b = a.

Front

What is the Transitive Property in mathematics?

Back

If a = b and b = c, then a = c.
