What is a linear equation?

Front

Define slope in the context of a linear equation.

Back

The slope of a linear equation represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It is calculated as the rise over run between two points on the line.

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. It represents the value of y when x is 0.

Front

How do you find the point of intersection of two linear equations?

Back

To find the point of intersection, solve the system of equations formed by the two linear equations simultaneously. This can be done using substitution or elimination methods.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution to the system is the set of values that satisfy all equations simultaneously.

Front

Explain the concept of dependent and independent variables.

Back

In a function, the independent variable is the input (often x), while the dependent variable is the output (often y) that depends on the value of the independent variable.

What is the formula to calculate the total amount in a savings account after a certain number of weeks?

Back

The total amount in a savings account can be calculated using the formula: Total Amount = Initial Amount + (Weekly Change * Number of Weeks).

How do you represent a weekly spending pattern in a linear equation?

Front

What is the significance of the coefficients in a linear equation?

Back

The coefficients in a linear equation indicate the rate of change of the dependent variable with respect to the independent variable. They determine the slope of the line.

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts. This means they will never intersect.
