What is a system of linear equations?

• A set of two or more linear equations with two or more variables

• An equation with no variables

• A single equation with one variable

• A quadratic equation

How do you determine if an ordered pair is a solution to a system of equations?

• By graphing the equations and checking the intersection

• By substituting the pair into each equation to see if both are satisfied

• By solving the equations algebraically

• By checking if it satisfies only one equation

What should you do if an ordered pair does not satisfy the first equation in a system?

• Graph the equations

• Assume it is a solution

• Check the second equation anyway

• Do not check the other equations

When graphing two lines, what does the point of intersection represent?

• The x-intercept of the lines

• The midpoint of the lines

• The solution to the system of equations

• The y-intercept of the lines

How can you verify the solution of a system of equations?

• By solving the equations separately

• By checking if the solution satisfies both equations

• By checking if the solution satisfies only one equation

• By graphing only one equation

What is the importance of checking your graphing accuracy?

• To ensure the lines are parallel

• To confirm the point of intersection is correct

• To find the slope of the lines

• To determine the y-intercept

What does it mean if two lines intersect at the y-intercept?

• They have the same starting point

• They have the same slope

• They have no solution

• They are parallel

In a word problem, what does the solution to a system of equations represent?

• The total number of variables

• The point where the lines are parallel

• The midpoint of the graph

• The point where the conditions of the problem are met

If two people are reading at different rates, how can you determine when they will be on the same page?

• By comparing their starting pages

• By adding their reading rates

• By subtracting their reading rates

• By graphing their progress and finding the intersection

What is the significance of the y-intercept in a linear equation?

• It is the midpoint of the line

• It determines the slope of the line

• It is the starting point of the line on the y-axis

• It is where the line crosses the x-axis
