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 of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

Front

What is a function?

Back

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

Front

How can you determine if a relation is a function from a graph?

Back

A relation is a function if any vertical line drawn through the graph intersects it at most once (Vertical Line Test).

Front

What is the meaning of the term 'domain' in a function?

Back

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

Front

What is the meaning of the term 'range' in a function?

Back

The range is the set of all possible output values (y) for the function.

Front

How do you evaluate a function at a specific value?

Back

To evaluate a function f(x) at a specific value a, substitute x with a in the function's equation.

Front

What is the relationship between the coefficients of a linear equation and its graph?

Back

The coefficients determine the slope and y-intercept, affecting the steepness and position of the line on the graph.

Front

What does it mean for a function to be linear?

Back

A linear function is one that graphs to a straight line, characterized by a constant rate of change (slope).
