What is the mode of a set of data?

Back

The mode is the value that appears most frequently in a data set.

Front

How do you determine the mode from the following data: 560, 580, 590, 640?

Back

The mode is 590, as it appears most frequently.

Front

What is a reasonable conclusion from a survey exploring the relationship between gender and band class?

Back

A reasonable conclusion is that more than half of the band members in the class are girls.

Front

What are x-intercepts in a graph?

Back

X-intercepts are the points where the graph crosses the x-axis, meaning y=0.

Front

Find the x-intercepts for the equation y = x^2 - 4. What are they?

Back

The x-intercepts are x=0 and x=4.

Front

What does it mean for an ordered pair to satisfy an equation?

Back

An ordered pair satisfies an equation if, when substituted into the equation, it makes the equation true.

Front

Which ordered pair satisfies the equations y = 2x - 2 and y = x + 1?

Back

The ordered pair (4, 1) satisfies both equations.

Front

What is the solution to a system of equations?

Back

The solution is the point where the graphs of the equations intersect.

Front

How do you find the solution to the system of equations: y = 2x - 2 and y = x + 1?

Back

By solving the equations simultaneously, the solution is (1, -1).

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.
