Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line. It has the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the function. It indicates how much the y-value changes for a unit change in the x-value.

Front

What is the y-intercept?

Back

The y-intercept is the point where the line crosses the y-axis. It is the value of y when x = 0.

Front

How do you find the value of a function at a given point?

Back

To find the value of a function at a given point, substitute the x-value into the function's equation and solve for y.

Front

What is a graph?

Back

A graph is a visual representation of data or a function, showing the relationship between two variables.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as the x-values increase, the y-values decrease.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the x-values increase, the y-values also increase.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair (x, y).

Front

How do you interpret a graph?

Back

To interpret a graph, analyze the axes, identify the shape of the graph, and determine the relationship between the variables represented.

Front

What is a function?

Back

A function is a relation that assigns exactly one output (y) for each input (x).
