What is a function in mathematics?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

How can you determine if a set of ordered pairs represents y as a function of x?

Back

A set of ordered pairs represents y as a function of x if no two pairs have the same x-value with different y-values.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run).

Front

What is the equation of a line in slope-intercept form?

Back

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is the y-intercept of a line?

Back

The y-intercept of a line is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

How do you find the coordinates of a point on a line given its equation?

Back

To find the coordinates of a point on a line, substitute a value for x into the equation and solve for y.

Front

What is the relationship between distance and cost in a taxi fare problem?

Back

In a taxi fare problem, the cost is typically a function of the distance traveled, often represented by a linear equation.

Front

What is the significance of ordered pairs in a function?

Back

Ordered pairs (x, y) represent the relationship between the input x and the output y in a function.
