Front

What does the graph of the equation x = -4 look like?

Back

A vertical line on the graph.

Front

What is the solution to the system of equations y = 4x + 3 and 2x - 3y = 21?

Back

The solution is (-3, -9).

Front

What is the domain of the function c = 34.95u + 6.25 for 8 to 12 players?

Back

The domain is {8, 9, 10, 11, 12}.

Front

Identify the slope and y-intercept of the equation y = 3/2x + 3.

Back

Slope: 3/2, Y-intercept: 3.

Front

If y varies directly with x, what is the constant of variation when y = 7 and x = 4?

Back

The constant of variation is 1.75.

Front

What is the definition of a variable in algebra?

Back

A symbol used to represent an unknown value.

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 find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope is calculated as (y2 - y1) / (x2 - x1).

Front

What does it mean for two lines to be parallel?

Back

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

Front

What is the solution to the equation 2x + 3 = 11?

Back

The solution is x = 4.
