8th grade math semester review

Front

What is the definition of slope?

Back

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

Front

What is the formula for calculating slope?

Back

The formula for slope is m = (y₂ - y₁) / (x₂ - x₁).

Front

How does the translation (x-4, y) affect the position of a point?

Back

The translation (x-4, y) moves the point 4 units to the left.

Front

What is the Angle Relationship that occurs when two lines intersect?

Back

Vertical angles are formed when two lines intersect, and they are equal.

Front

How do you determine the slope from two points?

Back

Use the formula m = (y₂ - y₁) / (x₂ - x₁) to find the slope.

Front

What does 'rise over run' mean in the context of slope?

Back

'Rise over run' refers to the vertical change (rise) divided by the horizontal change (run) between two points on a line.

Front

What is the significance of vertical angles in geometry?

Back

Vertical angles are always equal and are formed by the intersection of two lines.

Front

What happens to the slope if the line goes down from left to right?

Back

The slope is negative if the line goes down from left to right.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

How do you find the slope of a line given its equation in slope-intercept form?

Back

In the equation y = mx + b, m represents the slope.
