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 is the point(s) where the equations intersect.

Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other variable.

Front

What does it mean for a system of equations to have no solution?

Back

A system has no solution when the equations represent parallel lines that never intersect.

Front

What is the meaning of a solution to a system of inequalities?

Back

A solution to a system of inequalities is any point that satisfies all inequalities in the system.

Front

How do you determine the rate of change from a table of values?

Back

The rate of change can be calculated by finding the difference in the output values divided by the difference in the input values over a specific interval.

Front

What is a quadratic function?

Back

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola represented by the quadratic function.

Front

What does it mean for a function to be increasing or decreasing?

Back

A function is increasing when its output values rise as the input values increase, and decreasing when its output values fall as the input values increase.

Front

What is the significance of the y-intercept in a linear equation?

Back

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

Front

How do you graph a linear equation?

Back

To graph a linear equation, find two or more points that satisfy the equation and connect them with a straight line.
