Front

What is the constant in a linear graph?

Back

The constant is the y-value where the line crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.

Front

What does the point (0,0) represent in a graph?

Back

The point (0,0) is known as the origin, representing zero values for both the x and y coordinates.

Front

How do you calculate earnings based on hours worked?

Back

To calculate earnings, multiply the hourly wage by the number of hours worked.

Front

What does it mean for a table to be proportional?

Back

A table is proportional if the ratio of the dependent variable to the independent variable is constant.

Front

What does the point (2, 94) represent in a savings context?

Back

The point (2, 94) indicates that after 2 weeks, a total of $94 has been saved.

Front

Define a linear relationship in mathematics.

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph.

Front

What is the formula for calculating the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What is a proportional relationship?

Back

A proportional relationship is one where two quantities maintain a constant ratio to each other.

Front

How do you determine if a set of data points is proportional?

Back

To determine if data points are proportional, check if the ratios of corresponding values are equal.

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the value of y when x is zero.
