Chapter 6 & 7 Review - Integrated Ib

Front

What is a system of equations?

Back

A set of two or more equations with the same variables that are solved together.

Front

What does it mean if a system of equations has no solution?

Back

It means that the lines represented by the equations are parallel and never intersect.

Front

Define alternate exterior angles.

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What is the relationship between corresponding angles when two lines are parallel?

Back

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

Front

How do you find the missing side in similar figures?

Back

Use the ratio of the corresponding sides of the similar figures to set up a proportion.

Front

What is the formula for solving a system of linear equations using substitution?

Back

Solve one equation for one variable and substitute that expression into the other equation.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if their measures add up to 180 degrees.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope and different y-intercepts.
