What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph intersects the y-axis. It is represented as (0, y).

Front

What does a system of linear equations represent graphically?

Back

A system of linear equations represents the intersection points of the lines on a graph, where each line corresponds to an equation.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you find the break-even point in a cost-revenue graph?

Back

The break-even point is found where the cost and revenue lines intersect on the graph.

What is a linear function?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written as (x, y).

Front

What is an inequality?

Back
